oVirt 4.2.0 Release Notes

The oVirt Project is pleased to announce the availability of the 4.2.0 Release as of December 19, 2017.

oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

This release is available now for Red Hat Enterprise Linux 7.4, CentOS Linux 7.4 (or similar).

If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page.

For complete installation, administration, and usage instructions, see the oVirt Documentation.

For a general overview of oVirt, read the About oVirt page.

oVirt 4.2.0 Release Notes
1. What’s New in 4.2.0?

What’s New in 4.2.0?

The Administration Portal has been redesigned using Patternfly. The new user interface is more intuitive and user-friendly, and features improved performance.
A new VM Portal for non-admin users. Built with performance and ease of use in mind, the new VM portal delivers a more streamlined experience.
A High Performance VM type has been added to the existing “Server” and “Desktop” types. The new type enables administrators to easily optimize a VM for high performance workloads.
The oVirt Metrics Store is a real-time monitoring solution providing complete infrastructure visibility, for data-based decision making and faster issue resolution.
oVirt now supports VM connectivity via software defined networks - implemented by Open Virtual Network (OVN). OVN is automatically deployed to hypervisors, and made available for VM connectivity. Networks can be defined in the UI, over REST, or within the ManageIQ Gaprindashvili release (now in RC).
Support for Nvidia vGPU, a technology that enables users to shard a GRID-capable physical GPU into several smaller instances, for GPU-accelerated workloads.
The ovirt-ansible-roles package helps users with common administration tasks. All roles can be executed from the command line using Ansible, and some are executed directly from oVirt engine.
oVirt will now use PostgresSQL 9.5 as its database, for improved performance.
Support for LLDP, enabling oVirt hosts to gather information from their networking interfaces, for improved network configuration. The information can be displayed both in the UI and via an API.
Snapshots can be uploaded and downloaded via the REST API (and the SDKs).
A new self-hosted engine wizard UI. Among other improvements it now enables users to review and edit their inputs before beginning the deployment process.
Hosted Engine Ansible-based deployment (in Beta),using “ovirt-hosted-engine-setup –ansible”, is a new method to deploy a hosted engine. It reduces deployment issues, and will enable users to benefit from future features such as single storage for the hosted engine and other VMs, live storage migration, and improved hosted engine VM editing capabilities. We expect it to become the default provisioning flow for Hosted Engine and would be glad to get feedback on its functionality!
The ipa-client package is now installed on hosts and included in the oVirt Node. This identity management feature provides users with a seamless experience while moving between Cockpit and other products.
Virt-v2v now supports Debian/Ubuntu based VMs, in addition to EL and Windows-based VMs.
Restored support for Gluster ISO domains.
Improved Affinity Label management tools were incorporated into the cluster, host, and VM’s edit dialogs.
oVirt now features Gluster 3.12.
oVirt’s hyperconverged solution now enables a single replica Gluster deployment.
Improved self-hosted-engine iSCSI deployment.
A new driver for Win10, for seamless remote access to VMs, and improved performance.
Administrators can now use the Administration Portal to remove a LUN from the storage domain.
Instead of polling libvirt every 2 seconds to get the used disk for each thin disk, VDSM now uses events, for a noticeable increase in efficiency on a host with tens or hundreds of VMs.
In addition, oVirt 4.2.0 features host scalability improvements, for high density setups.

To learn about features introduced before 4.2.0, see the release notes for previous versions.

No Fedora support

Regretfully, Fedora is not supported anymore, and RPMs for it are not provided. At this point, we only try to fix problems specific to Fedora if they affect developers. For some of the work to be done to restore support for Fedora, see also tracker bug 1460625.

EPEL

Don’t enable all of EPEL on oVirt machines.

The ovirt-release package enables the EPEL repositories and includes several specific packages that are required from there. It also enables and uses the CentOS SIG repos, for other packages.

If you want to use other packages from EPEL, you should make sure to use includepkgs and add only those you need avoiding to override packages from other repos.

Release Note

VDSM

BZ 1438822 The discard_enable flag should not be used anymore in oVirt 4.2
With this update, support for configuring “Discard After Delete” per host has been dropped. This also drops the value “discard_enable” from the VDSM configuration file. The “Discard After Delete” feature now needs to be configured per block storage domain. For more information see discard afterdelete

oVirt Web UI

BZ 1507406 Rebase ovirt-web-ui to 1.3.z
With this update, the Virtual Machine Portal has been updated to version 1.3.1 and adds the following functionality:
- Use of “AlwaysFilterResultsForWebUi” engine configuration parameter
- BnB (Brand new Branding) - aligned with ovirt-engine
- Smartcard Enabled option
- SSH public key
- Guest Operating System names as labels
- i18n improvements, first translations
- multiple fixes and minor UI enhancements

oVirt Engine

BZ 1490784 blacklist RHEL <6.9 from machine types pseries-rhel7.4.0+
With this update, Red Hat Enterprise Linux versions less than version 6.9 are not supported in clusters using the machine type pseries-rhel7.4.0 or newer (4.1+). It is now blacklisted and cannot be started due to there being no CPU architecture available. A new definition of guest operating system for Red Hat Enterprise Linux versions 6.9 and greater has been added and should be used for Red Hat Enterprise Linux 6 guests in Red Hat Virtualization 4.1 and greater clusters. Also note that the cluster compatibility version 4.2 requires the pseries-rhel7.5.0 machine type, which is introduced by Red Hat Enterprise Linux 7.5 hosts. Until they are available you need to keep using the 4.1 cluster compatibility level.
BZ 1425935 [RFE] Add SSO client command line registration tool
This update includes the new ovirt-register-sso-client-tool command-line tool to register SSO clients.

When running the tool, the user is prompted to enter the client ID, callback prefix, and the certificate location. A new entry is created in the sso_clients table if one does not exist, or the existing one with the same client ID is updated. The client_secret which is written to a temporary file should be noted and used by the client.

The client secret in the sso_clients table is encrypted and is for SSO internal use only.
BZ 1463083 RESTAPI - Attaching a storage domain to 4.0 DC fails due to discard after delete is now True by default but not supported
Previously, when adding a new data storage domain without stating the values of Discard After Delete (DAD) and storage format, their default values were previously calculated according to the data center version of the host that added the storage domain. Discard After Delete was set to true for a data center greater than or equal to Red Hat Virtualization 4.1, otherwise it was set to false. The storage format was set V4 for the a data center greater than or equal to Red Hat Virtualization 4.1, otherwise it was set to V3. This was a bad heuristic since the data center of the host that added the domain is a random data center and it is not necessarily the data center that the domain will be later attached to. Now, the logic has been changed so that the default storage format for new data domains will be the latest format, currently it is V4. For non-data domains, nothing has changed V1 was and will remain the default value. The default value of Discard After Delete will be calculated according to the storage format and is set to true for storage formats greater than or equal to V4, otherwise it is set to false.
BZ 1420310 User actions should succeed regardless of ‘filter’ parameter
With this update, an issue with the the way that the API supports the ‘filter’ parameter to indicate if results should be filtered according to the permissions of the user has been corrected. Previously, due to the way this was implemented, non-admin users needed to set this parameter for almost all operations, as the default value was ‘false’. Now, to simplify the task for non-admin users, this patch changes the default value to ‘true’, but only for non-admin users. If the value is explicitly given in a request it will be honored.This is a backwards compatibility breaking change, as clients that used non-admin users and did not explicitly provide the ‘filter’ parameter will start to behave differently. However, this is unlikely, as calls from non-admin users without the ‘filter=true’ are almost useless. For those unlikely cases where this may be a problem, the patch also introduces a new ‘ENGINE_API_FILTER_BY_DEFAULT’ configuration parameter:

#
# This flags indicates if ‘filtering’ should be enabled by default for
# users that aren’t administrators.
#
ENGINE_API_FILTER_BY_DEFAULT=”true”

If it is necessary to revert to the behavior of previous versions of the engine, it can be achieved by changing this parameter in a configuration file inside the ‘/etc/ovirt-engine/engine.conf.d’ directory. For
example:

# echo ‘ENGINE_API_FILTER_BY_DEFAULT=”false”’ > <br> /etc/ovirt-engine/engine.conf.d/99-filter-by-default.conf

# systemctl restart ovirt-engine

Enhancements

oVirt Host Dependencies

BZ 1490041 [RFE] Provide IdM client software in RHVH
ipa-client package is now installed on hosts and is included in oVirt Node / RHV-H
This allows to integrate cockpit certificate signing and SSO with Red Hat IdM and adding the host to IdM realm.

OTOPI

BZ 1411100 [RFE] Change timestamp format to include timezone for logs
From now on, all timestamp records for otopi-based tools logs (including engine-setup, host-deploy, and hosted-engine –deploy) will contain a time zone to ease correlation between logs on the Manager and hosts. They will also now include the fraction of a second. Previously they contained a timestamp without a time zone and fraction of a second, for example:

2017-04-03 09:56:58 DEBUG otopi.context context.dumpEnvironment:760 ENVIRONMENT DUMP - BEGIN

From now on there will always be a comma and fraction of a second after the seconds part, and a timezone identifier at the end of the timestamp part, for example:

2017-04-05 10:41:08,500+0300 DEBUG otopi.context context.dumpEnvironment:760 ENVIRONMENT DUMP - BEGIN
BZ 1518689 [RFE] otopi should log on failure list of network connections
otopi now optionally logs the list of network connections on the machine after failures. Enable this by installing the optional package otopi-debug-plugins. This can help debug failures to start network services due to “Address already in use” errors.

oVirt Engine SDK 4 Ruby

BZ 1317450 [RFE] Have a policy for autoresume of VMs paused due to IO errors (stay paused, turn off, restart with defined time out time)
Feature:
Previously, if the VM has been paused due to IO Error, there was no way how to configure what should happen after the storage gets fixed. The only option was “auto resume”, which resumed the VM. This feature adds two more options configurable per VM: “Kill” and “Leave Paused”.

Reason:
There are ways how the “auto resume” together with HA VM using VM lease could lead to split brain. Other reason is that it can interfere with custom HA solutions.

Result:
Now the user can configure 3 resume policies for VMs:
- auto resume (the one which used to be the only one)
- leave paused
- kill

VDSM

BZ 1317450 [RFE] Have a policy for autoresume of VMs paused due to IO errors (stay paused, turn off, restart with defined time out time)
Feature:
Previously, if the VM has been paused due to IO Error, there was no way how to configure what should happen after the storage gets fixed. The only option was “auto resume”, which resumed the VM. This feature adds two more options configurable per VM: “Kill” and “Leave Paused”.

Reason:
There are ways how the “auto resume” together with HA VM using VM lease could lead to split brain. Other reason is that it can interfere with custom HA solutions.

Result:
Now the user can configure 3 resume policies for VMs:
- auto resume (the one which used to be the only one)
- leave paused
- kill
BZ 1181665 [RFE][scale] Use events and not polling to detect disk usage [using the improvement from platform bug 1181659]
Feature:
Vdsm can make use of the event added in libvirt 3.2.0 to learn about the allocation of block chunked drives and improve the efficiency of the thin provisioning implementation.

Reason:
To implement the thin provisioning of block chunked drives, Vdsm needs to periodically monitor the allocation of the backing volumes. This could be done either polling libvirt or registering events. The second option is available since libvirt 3.2.0 and it is way more efficient than the first.

Result:
When using events, Vdsm consumes much less system resources.
BZ 1376843 [RFE] Implement a keep-alive with reconnect if needed logic for the python jsonrpc client
jsonrpc python client is now able to reconnect in case jsonrpc server has restarted.
BZ 1205739 [RFE][DR] - Allow recovering an imported domain without an UP DC
Cause:
Can not attach storage domain with “dirty” SP_UUID.
This process fails since the host is not yet connected
to a storage pool and therefore there is no host id which we can use to take a lock on the storage domain.

Consequence:
When attempting to attach an imported storage domain to a Data Center.

Fix:
Enable the possibility to force detach a storage domain
even if the host is not yet connected to the storage pool.

Result:
Enable the option for force detach a storage
domain and clean its SP_UUID before we will want to connect it to the storage pool.
BZ 1391859 [RFE] When creating thick allocated disks on file-based storage, use ‘-o preallocation=falloc’ instead of ‘dd’ with zeros.
New feature greatly reduces the time required to create thick allocated disks on file-based storage.
BZ 1228543 [RFE] hot-unplug memory
Previously, it was only possible to add memory to a running virtual machine (VM). To remove memory, the VM had to be shut down.
In this release, it is now possible to hot unplug memory from a running VM, provided that certain requirements are met and limitations are considered.
BZ 1168327 Live Merge: optimize internal volume size
After live merge, the base volume is reduced to its optimal size.
BZ 1430799 Create script to restore original network configuration of removed vdsm host
Feature:
Provide tools for simple removal of networks configured by oVirt on a host.

Reason:
One could add a host into Engine and one minute later decide to remove it. But the host would have ovirtmgmt bridge and various VDSM network hacks which are not clear how to remove.

Result:
vdsm-tool now provides commands for VDSM network cleanup, particularly vdsm-tool clear-nets and vdsm-tool dummybr-remove. One could remove networks configured by VDSM following the steps below. Note that vdsm service is not required to be running:

1. To prevent loss of connectivity it might be needed to exclude default route network from cleanup. Look for a network providing default route (ovirtmgmt by default):
# vdsm-tool list-nets
…
ovirtmgmt (default route)
…

2. Remove all networks configured by VDSM except for the default network.
# vdsm-tool clear-nets –exclude-net ovirtmgmt

3. Remove libvirt dummy bridge ;vdsmdummy;
# vdsm-tool dummybr-remove

4. Host should be clean, you can remove vdsm now.
BZ 1367806 [RFE] - Add “blkdiscard” as a new method to zero volumes
A new VDSM parameter enables a host to remove a disk/snapshot on block storage, where “Wipe After Delete” is enabled, in much less time than the “dd” command, especially if the storage supports “Write same.”
BZ 1335642 [RFE] Users should be able to seal VMs from RHEV-M
The feature is documented here

oVirt Cockpit Plugin

BZ 1493851 [RFE] Suggest to give a hint when HE with one host don’t permit to put itself into local maintenance.
Feature: The Hosted Engine management page in cockpit-ovirt now presents a warning message if only one host is available in the hosted engine cluster, preventing it from being moved to local maintenance.

Reason: Hosted Engine does not allow moving the last (or only) host running hosted engine to local maintenance, only global.

Result: cockpit-ovirt now reflects the options supported by hosted engine.

imgbased

BZ 1503148 [RFE] translate between basic ntp configurations and chrony configurations
BZ 1420068 [RFE] RHV-H should meet NIST 800-53 partitioning requirements by default
In this release, Red Hat Virtualization Host supports NIST SP 800-53 partitioning requirements to improve the security. Environments upgrading to Red Hat Virtualization 4.2 will also be configured to match NIST SP 800-53 partitioning requirements.

oVirt Engine SDK 4 Python

BZ 1405805 [RFE] - Streaming API should support upload of disk snapshots
Support uploading of disk snapshots using ovirt-imageio. Full details in feature page
BZ 1483305 [RFE] - Streaming API should support download of disk snapshots
The REST API supports the download of disk snapshots.

oVirt Engine

BZ 1317450 [RFE] Have a policy for autoresume of VMs paused due to IO errors (stay paused, turn off, restart with defined time out time)
Feature:
Previously, if the VM has been paused due to IO Error, there was no way how to configure what should happen after the storage gets fixed. The only option was “auto resume”, which resumed the VM. This feature adds two more options configurable per VM: “Kill” and “Leave Paused”.

Reason:
There are ways how the “auto resume” together with HA VM using VM lease could lead to split brain. Other reason is that it can interfere with custom HA solutions.

Result:
Now the user can configure 3 resume policies for VMs:
- auto resume (the one which used to be the only one)
- leave paused
- kill
BZ 1459134 [RFE] Rebase engine-setup on PostgreSQL >= 9.5
With this release, the engine now requires PostgreSQL 9.5 or later, which provides new features and better performance. The engine-setup tool can help upgrade an existing database to Software Collections PostgreSQL 9.5, as well as use that version for new setups.
BZ 1507277 [RFE][DR] - Vnic Profiles mapping in VMs register from data storage domain should be supported also for templates
Feature: Allow selecting vnic profiles for templates when registering them to the engine from a storage domain.

Reason: This was possible for vm’s but not for templates until now

Result: the user may configure the vnic profiles of a template upon register
BZ 1319758 [RFE] Allow uploading a pre-existing VM image (OVA) into the environment
Feature:
Enable uploading an OVA into an oVirt data center.

Reason:
Simplify the process of importing a virtual machine that was created out of the data center.

Result:
It is now possible to import an OVA that is accessible to at least of the hosts in the data center into a virtual machine in oVirt.
BZ 1506697 Don’t freeze the VM when taking a live snapshot in LSM
Feature:
VM file system will not be frozen in case the snapshot is taken is the auto-generated snapshot that is created during live storage migration

Reason:
Speed up the process of live storage migration
BZ 1514942 Add option to specify the host when uploading an image via the API
Added the ability to specify a host in the ImageTransfer entity. This is useful if the user prefers to use a specific host for uploading.

An example for the python sdk:
transfer = transfers_service.add(
types.ImageTransfer(
image=types.Image(
id=disk.id
),
direction=types.ImageTransferDirection.DOWNLOAD,
host=system_service.hosts_service().list(search=’name=myhost’)[0]
)
)
BZ 1480433 [RFE] Indicate host needs to be reinstalled to push new configurations.
There are several cluster or host settings which will require host reinstallation if the settings are changed.

A host must be reinstalled if you any of its following settings are changed:
- Turn off/on Kdump integration.
- Change command line parameters.

All hosts in a cluster must be reinstalled if you change the firewall type of the cluster.

In addition to the existing documentation and Warning event, an exclamation mark icon will now be added to each host that needs to reinstalled. When exclamation mark icon is shown, you can find the details about it in Host detail view within Action Items section.
BZ 1454287 [RFE] Add UI support to remove a LUNs from a data domain
BZ 1496382 [RFE][REST API] Support memory hot unplug via REST
please see
* hot unplug memory
* http://ovirt.github.io/ovirt-engine-api-model/master/#types/vm/attributes/memory
* http://ovirt.github.io/ovirt-engine-api-model/master/#types/memory_policy/attributes/guaranteed
BZ 1405805 [RFE] - Streaming API should support upload of disk snapshots
Support uploading of disk snapshots using ovirt-imageio. Full details in feature page
BZ 1416141 [RFE] Use JDK and EE builtins for scheduled tasks and threads
Use JBoss ManagedThreadFactory, ManagedExecutorService and ManagedScheduledExecutorService instead of Java EE ExecutorService and Quartz to schedule jobs.

There are two ManagedExecutorServices in engine commandCoordinator and hostUpdatesChecker.

The size of the commandCoordinator executor service is defined by config variable COMMAND_COORDINATOR_THREAD_POOL_SIZE. The default size if 10. To change the size create a new conf file 99-coco-thread-pool.conf in /etc/ovirt-engine/engine.conf.d/

The size of the hostUpdatesChecker executor service is defined by config variable HOST_CHECK_FOR_UPDATES_THREAD_POOL_SIZE. The default size if 5. To change the size create a new conf file 99-host-thread-pool.conf in /etc/ovirt-engine/engine.conf.d/

Management clients, such as the WildFly CLI, can also be used to configure ManagedExecutorService instances commandCoordinator and hostUpdatesChecker with out having to restart engine.

The ‘engine’ executor service size is define by config variables ENGINE_THREAD_POOL_MIN_SIZE and ENGINE_THREAD_POOL_MAX_SIZE. The default value for ENGINE_THREAD_POOL_MIN_SIZE is 50 and default value for ENGINE_THREAD_POOL_MAX_SIZE is 500. To change the value permanentaly create a conf file 99-engine-thread-pool.conf in /etc/ovirt-engine/engine.conf.d/.

jconsole can be used to change the size of the ‘engine’ executor service with out having to restart engine.

‘engineScheduled’ ManagedScheduledExecutorService size is define by config variable ENGINE_SCHEDULED_THREAD_POOL_SIZE. The default value is 100. To change the value
permanentaly create a conf file 99-engine-scheduled-thread-pool.conf in /etc/ovirt-engine/engine.conf.d/

Management clients, such as the WildFly CLI, can also be used to configure ManagedScheduledExecutorService instance ‘engineScheduled’ with out having to restart engine.

Engine creates a log entry of the thread pool usage as define by the config variable THREAD_POOL_MONITORING_INTERVAL_IN_SECONDS. The default value is 600 seconds. So every 10 minutes a log entry is created for each pool showing the thread pool usage.

Thread pool ‘engine’ is using 7 threads out of 500, 1 threads waiting for tasks and 0 tasks in queue.
Thread pool ‘engineScheduled’ is using 0 threads out of 100 and 100 tasks are waiting in the queue.
Thread pool ‘engineThreadMonitoring’ is using 1 threads out of 1 and 0 tasks are waiting in the queue.
BZ 1492067 [RFE] add mdev_type to host devices tab
Feature:
Add the “mdev_type” column to host devices list.

Reason:
If a user wanted to pass through an mdev to a VM, he needed to find the mdev_type of the device by SSH-ing to the hypervisor and run a VDSM command to get this information.

Now, this information is exposed in the UI.

Result:
Now the user can find the mdev_type in the same UI which is used to set it to the VM.
BZ 1490866 [RFE] Deprecate iptables firewall type for hosts
Using an iptables firewall on virtualization hosts is deprecated in Red Hat Virtualization 4.2 and will be completely removed in Red Hat Virtualization 4.3. Administrators should switch to a firewalld firewall which is introduced in Red Hat Virtualization 4.2.

To make the switch to firewalld more visible, Red Hat Virtualization Manager will go all over existing clusters every 30 days and raise warning events to the audit log. Another warning message has been added to engine-config help for all iptables related settings.
BZ 1457239 [RFE] Provide “High Performance VM” Profile to ovirt
Previously, it was difficult to configure a virtual machine (VM) to run with high performance workloads via the Administration Portal as it involved understanding and configuring a large number of settings. In addition, several features that were essential for improving the VM’s performance were not supported at all, for example, huge pages and IO thread pinning.

In this release, a new optimization type called High Performance is available when configuring VMs. It is capable of running a VM with the highest possible performance, with performance metrics as close to bare metal as possible. When the customer selects High Performance optimization, some of the the VMs settings are automatically configured while other settings are suggested for manual configuration.
BZ 1185782 REST-API is missing image total size attribute
BZ 1205739 [RFE][DR] - Allow recovering an imported domain without an UP DC
Cause:
Can not attach storage domain with “dirty” SP_UUID.
This process fails since the host is not yet connected
to a storage pool and therefore there is no host id which we can use to take a lock on the storage domain.

Consequence:
When attempting to attach an imported storage domain to a Data Center.

Fix:
Enable the possibility to force detach a storage domain
even if the host is not yet connected to the storage pool.

Result:
Enable the option for force detach a storage
domain and clean its SP_UUID before we will want to connect it to the storage pool.
BZ 1459908 Rest API does not report network statistics host “data.current.tx, data.current.rx”
Feature:

The precision of the rx_rate, tx_rate, rx_drop and tx_drop of virtual and host network interfaces is increased.

Reason:

If traffic on the network interface is below the precision of the network interface statistics, it is not reflected in the statistics.

Result:

This enables to detect 100 times smaller traffic on network interface statistics.
BZ 1483305 [RFE] - Streaming API should support download of disk snapshots
The REST API supports the download of disk snapshots.
BZ 1096497 [restapi] Display image size and type for glance images missing in RESTAPI
Feature:
before that feature, Glance images returned by RESTAPI didn’t list their size and type (iso/disk).

Reason:
That information should be listed regarding to Glance images.

Result:
Glance images do list their type and size on REST API.
BZ 1372163 [RFE] Warn user about VMs that have pending snapshot removal retries
When live or cold merge fails, snapshot disks may be left in an illegal state. If VMs with illegal snapshot disks are shut down, they will not re-start. VMs with illegal snapshot disks are now marked with an exclamation mark and a warning message not to shut them down.
BZ 1475459 [RFE] Use Wildfly 11 for oVirt engine 4.2
BZ 1463633 [RFE] Provide support for data aggregation when fetching entities
This update enables Red Hat Virtualization API users to request that contents of some of the entity’s links be returned inline, inside the requested entity.

Previously, to retrieve multiple related objects from the API, the only alternative was to retrieve the first one, then send additional requests to retrieve the related objects. For example, if you needed a virtual machine and also the disks and NICs, you would need to first send a request like this:

GET /ovirt-engine/api/vms/123

And then send additional requests to get the disk attachments, the disks, and the NICs:

GET /ovirt-engine/api/vms/123/diskattachments GET /ovirt-engine/api/disks/456 GET /ovirt-engine/api/disks/789 GET /ovirt-engine/api/vms/123/nics

In environments with high latency, this increases the time required to retrieve the data. In addition, it also means that multiple queries have to be sent to the database to retrieve the data. To improve this, a new follow parameter has been introduced. This parameter is a list of links that the server should follow and populate. For example, the previous scenario will be solved sending this request:

GET /ovirt-engine/api/vms/123?follow=diskattachments.disks,nics

This will return the virtual machine with the disks and the NICs embedded in the same response, thus avoiding the multiple network round-trips. The multiple database queries will be avoided only if the server is modified to retrieve that data with the more efficient queries, otherwise the server will use the approach of calling itself to retrieve it, which won’t improve the number of queries.
BZ 1416491 [RFE] Add support for OpenID Connect in engine SSO
This update adds SSO support for OpenID Connect clients. The following new OpenID Connect discovery endpoint has been added so that clients can discover the authorization endpoints and OpenID Connect capabilities of the Manager:

https://<Manager&gt>/ovirt-engine/sso/openid/.well-known/openid-configuration

The following endpoint is used for client authorization and for obtaining the authentication code:

https://<Manager>/ovirt-engine/sso/openid/authorize

The following endpoint is used by clients to obtain the authentication token from the authentication code:

https://<Manager>/ovirt-engine/sso/openid/token

The following endpoint can used by clients to get details of the logged in user:

https://<Manager>/ovirt-engine/sso/openid/userinfo

The following endpoint can used by clients to get the keys used by SSO to sign the id_token returned from token and tokeninfo endpoints:

https://<Manager>/ovirt-engine/sso/openid/jwks
BZ 1456414 New domain should default to true on Discard After Delete
Up until now, the default value of the Discard After Delete field (DAD) was false.
That means that the UI checkbox was unchecked by default and creating a block storage domain via the REST-API without stating the value of DAD would have set it to false.

From now and on, the default value of DAD is true.
That means that the UI checkbox is checked by default and creating a block storage domain via the REST-API without stating the value of DAD will set it to true.
BZ 1228543 [RFE] hot-unplug memory
Previously, it was only possible to add memory to a running virtual machine (VM). To remove memory, the VM had to be shut down.
In this release, it is now possible to hot unplug memory from a running VM, provided that certain requirements are met and limitations are considered.
BZ 1177628 [RFE] pgsql logs are missing timestamps
engine-setup on new installations now configures postgresql to have a year worth of logs, and to include timestamps in the log records.
BZ 1321585 [RFE] Add option to deactivate storage domain only if ovf store was updated
Feature: Add ability to perform force maintenance to storage domain.

Reason:
Before this fix, storage domain could enter to maintenance even if OVF disks update failed.

Now, storage domain deactivation will fail in case of OVF update failure.
Force maintenance flag will supply the ability to deactivate the storage domain even in case of failure in OVF update.
BZ 1285456 [RFE] Persist column visibility and position in browser’s local storage
Feature: Persistent column widths, visibility, and order.

Reason: The user wants to be able to persist the width, visibility, and order of the columns in the grids on the webadmin UI.

Result: The width, visibility, and order is now stored in the browsers local storage so that reloads of the webadmin will not reset to the default width, visibility, and order.
BZ 1433676 [RFE] Add a link to CA certificate on the main landing page
A link to ovirt-engine’s CA certificate has been added to the welcome page.
BZ 1497612 New package: ovirt-cockpit-sso
Feature: Single Sign On to Host Console from Administration Portal

Reason: The administrator does not need to enter credentials when accessing host’s Cockpit session from Administration Portal.

Result:

The ovirt-cockpit-sso package provides Single Sign On (SSO) for Host COnsole (Cockpit) from Administration Portal.

To enable it on engine machine:
- install ovirt-cockpit-sso rpm (yum install ovirt-cockpit-sso)
- systemctl enable cockpit.socket
- systemctl enable ovirt-cockpit-sso
- systemctl start ovirt-cockpit-sso

The service listens on 9986/tcp port.

To try:
- have ovirt-cockpit-sso service running
- log into Administration Portal
- select Host
- click “Host Console” button
- optionally enable pop-up windows in you browser
- optionally confirm host’s fingerprint, if prompted
- new browser tab will appear with root Cockpit session

Please note, there should be either cockpit-machines or preferably cockpit-ovirt package installed on the selected RHV-H for best experience.
BZ 1399609 [RFE] optimization in choice of target host for migration
Feature:

The host selection dropdown in Migrate dialog now shows only hosts that can actually be used as destination for the selected VMs.

Reason:

Nicer user experience, the user does not have to think about affinity, hosted engine and other limitations. The logic pre-filters the list for him.
BZ 1420404 [RFE] add ability to warm restart a VM so that VM starts on the same host when it is run by Run Once and rebooted
Feature:
Make a warm restart of VMs started as run once from webadmin possible

Reason:
Previously, when the VM was started as run once, the restart from webadmin/rest api always caused the VM to be cold restarted. This feature renames the “Trap guest reboots” option in run once to “Rollback this configuration during reboots” and broadens its meaning. Now it allows one to configure if the VM should be warm or cold restarted during reboots both from webadmin/api and from inside of the guest.

Result:
The user can now decide if the VM should be warm or cold rebooted .
BZ 1168327 Live Merge: optimize internal volume size
After live merge, the base volume is reduced to its optimal size.
BZ 1428498 [RFE] Allow to search VMs by specific host they are pinned to.
Feature:
List all VMs pinned to a specific host, event if the VMs are offline.

Reason:
When a host with pinned VMs is moved to the maintenance mode, the VMs are shut down. There was no simple way for the user to know which VMs have to be started again, when the host is no longer in the maintenance mode.

Result:
The pinned VMs are listed in the Virtual Machines details tab of the Host entity.
There are buttons on top of the table, allowing the user to show only running VMs, pinned VMs or both.
BZ 1497619 [RFE] present per-interface LLDP data in SetupHostNetwork dialog
BZ 1442687 Hide expected network exceptions during host installation
BZ 1462811 [RFE] Execute Ansible role ovirt-host-deploy as a part of host installation/reinstallation to allow customization of this flow
The Ansible role ovirt-host-deploy[1] is now executed as part of the host installation/reinstallation flow. This role is included in ovirt-ansible-roles package and is installed on the Red Hat Virtualization Manager by default.

[1] /usr/share/doc/ansible/rols/ovirt-host-deploy/README.md
BZ 1441501 [RFE] Exposing configuration options within RESTAPI
Previously the Manager configuration options with user or admin access levels were only available to GWT clients. To obtain option values for non-GWT clients they are now exposed in the following REST API:

GET https://<ENGINE_FQDN>:/ovirt-engine/api/options/<OPTION_NAME>

Where <OPTION_NAME> is an existing configuration option name. The output of that call is a list of values. To obtain a value for only a specific client version, you need to specify the requested version as follows:

GET https://<ENGINE_FQDN>:/ovirt-engine/api/options/<OPTION_NAME>?version=<VERSION>

The Manager configuration options are not backward compatible and may differ for each Manager version, and therefore existing options may not be available. Options are exposed as read-only in the REST APIs, but some of them can be updated by using the engine-config command-line tool.
BZ 1231859 [RFE] notify user that KSM will not be enable till next time hypervisor enters maintenance mode
BZ 1366905 [RFE] Allow multiple IP’s / text fields for network filters, specifically clean-traffic
The engine already supports filtering the network communication of VMs. Now it is possible to configure the filter parameters using the REST-API.

See networkfilterparameters for details.
BZ 1207992 [RFE] Report IO errors to guests if the device is a CDROM
Virtual machines now stay operational when connectivity with CD-ROM images breaks. The error is reported to the guest operating system. Note that the configuration of the storage device may affect the time it takes to detect the error. In that period of time, the virtual machine is non-operational.
BZ 1241410 [RFE]- Add ‘passthrough’ column to the vNIC Profiles sub tab under Networks main tab
BZ 1169099 [RFE] secrets should be marked so near their definition
BZ 1434306 Can not remove Cinder provider even if the service is not available anymore.
Added ‘Force Remove’ button on Providers main view. Currently applicable only for volume providers (Cinder). Force removing a provider invokes the same operation as force remove of a storage domain. I.e. removing, from DB only, the provider along with all related entities (Storage Doamin, VMs, Templates, Disks).
BZ 1445681 No error pops when logging with a locked ovirt user account
For restapi clients the SSO authentication error is now added to the body of the response.

Example: Invalid password has been provided

curl -X GET -u admin@internal:123456 -H “Accept: application/xml” -H “Content-Type: application/xml” -H “Filter: true” http://127.0.0.1:8080/ovirt-engine/api/events

Response: The authentication error is now in the body of the response
```
<html>
   <head><title>Error</title></head>
   <body>access_denied: Cannot authenticate user 'admin@internal': The username or password is incorrect..</body>
</html>
```
BZ 1260480 [RFE] For ‘New’ host function, change ‘Address’ to ‘Hostname’
BZ 1160667 [RFE] Allow explicit dns configuration
The engine now supports explicit DNS configuration.
BZ 1439332 [backup] Engine backup stages to /tmp, can fill disk to 100% and down rhv-m
Feature:

engine-backup now allows to control the location of the temporary directory it uses, using the command line option –tmpdir=DIR or the env variable $TMPDIR.

Reason:

Before this change, engine-backup always used /tmp. If /tmp is full or close to being full, it wasn’t possible to tell engine-backup to use a different filesystem.

Result:

It’s now possible to run engine-backup even if /tmp is full by telling it to use a different location.
BZ 1433408 [RFE] Upgrade to latest checkstyle
BZ 1335642 [RFE] Users should be able to seal VMs from RHEV-M
The feature is documented here
BZ 1324532 [TEXT] - engine-upgrade-check should prompt user that while RPMs are updated the engine might not be updated if he didn’t run engine setup
Feature:
Provide a note to the user that the system may not be up to date after running engine-upgrade-check, if the user hasn’t run engine-setup following e.g. yum update.

Reason:
To ensure the user is aware that the system may not be fully up to date in certain cases, even when the engine-upgrade-check says that there is no upgrade available.

Result:
The warning message is now displayed.
BZ 1200963 [RFE] - Set non-mgmt network as Default Route
Feature:
The engine now enables configuring a non-management network as the default network route, using the UI instead of custom properties.

Reason:

Result:
BZ 1202311 [RFE] Present Rx/TX counter with coma separator between thousands
BZ 1488466 [RFE] Improve taskcleaner & unlock_entity execution
The taskcleaner and unlock_entity execution scripts have both had options for user, database, port and server names removed (-u, -d, -p, -s). Also there is no more need to export PGPASSWORD. All values are now obtained from the Manager configuration files.
BZ 1404389 [RFE] Need ability to refresh direct’s LUN size if it was added without a HOST parameter (or if the underlying storage was extended)
The engine can update a direct LUN’s missing or outdated information.
BZ 1146558 [RFE] Add the possibility to show iptables diff without interaction
BZ 1291177 [RFE] Display disk content type in the GUI, and allow searching/filtering according to it
In the Administration Portal, on the “Disks” tab, disks can be filtered by content type.
BZ 1514897 ‘KILL’ and ‘LeavePaused’ values could not be set for ‘Resume Behaviour’ of HA with no lease VMS
Feature:
Add resume behavior.

Reason:
Currently, if the VM gets paused due to storage error, if the storage gets back up again, it will always get un-paused. This is not always desirable (for example HA VMs restart is complicated, application level HA is complicated etc in this case).

Result:
Now there are 3 resume behaviors which can be configured per VM:
- kill (will kill the VM if it was paused for longer than 80s)
- LEAVE_PAUSED: do not touch it, leave it paused
- RESUME: the behavior which used to be the only one
BZ 1484060 [RFE] download monitoring in the WebAdmin
Added a progress bar to the status column of a disk on image download.
Also, the engine now finishes the download itself and doesn’t need the user to click on Download -> Cancel when he’s done to inform the engine about it.
Please see attached screencast to see the full process.
BZ 1477505 DR (site to site) - External LUN disks which are attached to VM should be part of the VM’s OVF
Feature:
Adding the ability to register VMs with external LUN disks

Reason:
Until now we ignored external LUN disks in VM’s OVF.
In oVirt 4.2 beta we added the support for those external LUN disks as part of the VM’s OVF.
With the added external LUN disks, oVirt gains the ability to register those VMs to the engine and add the external LUN disks of those VMs as well.

Result:
External LUN disks are now part of the VM’s OVF and can be added as part of the VM registration.
Keep in notice that once there is an existing external LUN disk in the ovirt-engine setup it must be removed before importing the VM, unless the partial_import flag is true.
In that case the VM will be registered without the external LUN disk
BZ 1489332 unlock_entity.sh does not report human readable output
Feature:

We have added command line parameter ‘-c’, using which column names will be shown in the output, so administrators will know what entity is identified by showed UUID.

Reason:

Result:
BZ 1491771 [RFE] Enable storage domain creation on a non replicated gluster volumes
RHEV-M allows storage domain creation with a single Gluster brick.
BZ 1489328 unlock_entity.sh -q does not support type “all”
Administrators had to pass specific entity type (“vm”, “disk” or “snapshot”) using -q option for each unlock_entity.sh invocation, but there was no way how to process all entity types within single invocation.

We have introduced new value “all” which can be passed using -q option to process all entity types at once.
BZ 1492706 ovirt-engine-appliance misses python2-pyOpenSSL which is required for OVN setup
The engine now requires OVN.

Didn’t check other OVN-related bugs, this can be mentioned in one of them instead of current.
BZ 1468965 Event log and engine spammed with ‘User admin@internal-authz logged in/out’ info messages
Feature:

All audit log messages around login or logout now contains not only username, but also IP address of the client which user is connecting from and ID of a session (if exists) to be able to distinguish between several connection from a single client.

Reason:

Result:
BZ 1126277 [Admin GUI] in ‘Add Users and Groups’ dialog the column title should be freeze.
BZ 1486006 Guest OS type is missing for SLES12 in RHV4.x / RHEV3.x
Feature:
Change the “SUSE Linux Enterprise Server 11” to “SUSE Linux Enterprise Server 11+” in the OS list

Reason:
There was a missing “SUSE Linux Enterprise Server 12”. Since there were no new values/settings for “SUSE Linux Enterprise Server 12”, it was enough to change the 11 to 11+

Result:
Now the OS list contains the value: “SUSE Linux Enterprise Server 11+”
BZ 1462629 [New UI] - Improve and align the whole ‘Network Interfaces’ dialog
Feature: The Networks Interfaces screen was redesigned

Reason: The previous Network Interfaces screen represented the network data in a table. That design did not match our UI redesign look and feel.

Result: The Network Interfaces screen was redesigned to use PatternFly listviews. Important NIC information is always visible on each NIC’s panel. More NIC details can be viewed by opening the expand/collapse sections on each list item.
BZ 1360192 [RFE] Image uploader: resume upload - user is asked to supply source, path and image type - all over again
Resuming a paused image download is now done ‘silently’ on browser session level. I.e. resuming a download won’t require selecting the file again until restarting the browser (after browser restart, we fallback to the previous behavior of selecting the file again).

oVirt Host Deploy

BZ 1461081 Deploy ovirt-host package only instead of single packages
BZ 1408942 Host deploy should install cockpit-ovirt.
oVirt Host Deploy now install and maintain updated cockpit-ovirt package on hypervisor hosts.

oVirt Engine Dashboard

BZ 1420039 [RFE] Create a Refresh button on Dashboard in Manager UI
Feature: Add a manual refresh button to the dashboard UI to update the display with currently available system summary information.

ovirt-engine-dwh

BZ 1459134 [RFE] Rebase engine-setup on PostgreSQL >= 9.5
With this release, the engine now requires PostgreSQL 9.5 or later, which provides new features and better performance. The engine-setup tool can help upgrade an existing database to Software Collections PostgreSQL 9.5, as well as use that version for new setups.
BZ 1409766 [RFE] Provide a tool to execute vacuum full on DWH database
This release adds a maintenance tool to run vacuum actions on the DWH database or specific tables.

The tool optimizes table stats and compacts the tables, resulting in less disk space usage. This allows for more efficient maintenance, and the updated table stats allow for better query planning.

Also provided is an engine-setup dialog that offers to perform vacuum during upgrades. This can be automated by the answer file.

oVirt Hosted Engine HA

BZ 1498327 HE host on EngineStarting -> EngineMaybeAway -> EngineDown cycle
Feature: Added caching of OVF storage location.

Reason: As OVF storage location raraely changes, we do not need to search for it on every monitoring loop iteration. Instead it can be saved and reused and expired only in case of error.

Result: Monitoring loop execution time decreased significantly
BZ 1149579 [RFE][hosted-engine-setup] [iSCSI support] allow selecting more than one iSCSI target
You can connect to more than one iSCSI target if you connect all the portals of an iSCSI portal group to enable multipathing before running the self-hosted engine deployment script. To be as backwards-compatible as possible and to avoid requiring changes in the deployment script, it saves the multiple IP and port values as a string composed of multiple comma-separated values with the same key used by the previous version. It assumes that the login is the same for all the portals.
BZ 1457471 Flood of getHardwareInfo (every 2 seconds or so) by ovirt-ha-agent
ovirt-ha-agent was renewing its json rpc connection to vdsm on each message using getHardwareInfo to verify it.
Now that the json rpc client internally supports a reconnect mechanism, there is not need to always create a fresh connection on ovirt-ha-agent side.
BZ 1417708 ovirt-ha-agent should reuse json-rpc connections
Feature:
In the past ovirt-ha-agent was opening a new connection each time it had to communicate with vdsm while now, for performance reasons, it can try to reuse an open connection if still valid.

Reason:
Performance reasons.

Result:
ovirt-ha-agent reuses an open json-rpc connection if available

oVirt Engine Metrics

BZ 1508481 [RFE] Add supervdsm to the collectd processes plugin
Feature:
Add supervdsm to the collectd processes plugin

Reason:
In order to monitor the supervdsm process.

Result:
An additional statistic under the processes plugin
BZ 1508480 [RFE] Add mom to the collectd processes plugin
Feature:
Add mom to the collectd processes plugin

Reason:
In order to monitor the mom process.

Result:
An additional statistic under the processes plugin
BZ 1508484 [RFE] Add ovirt-engine-dwhd to the collectd processes plugin
Feature:
Add ovirt-engine-dwhd to the collectd processes plugin

Reason:
In order to monitor the ovirt-engine-dwhd process.

Result:
An additional statistic under the processes plugin
BZ 1471833 [RFE] Allow passing extra ansible opts to oVirt Metrics shell script
Feature:
Allow extra ansible opts that are optional when running ansible-playbook directly.

Reason:
This adds additional options when configuring oVirt metrics.

Result:
Can now add ansible parameter when using configure_ovirt_machines_for_metrics.sh
BZ 1446480 [RFE] add “Uptime” Column to oVirt Metrics Store
Feature:
This patch loads the uptime collectd plugin that reports the system uptime.

Reason:

Result:

oVirt Hosted Engine Setup

BZ 1418579 Use selinux when building ovirt-appliance
Feature:
Set SELinux to enforcing in ovirt-appliance

Reason:
Enhance security for the ovirt-appliance

Result:
SELinux is now being enforced
BZ 1149579 [RFE][hosted-engine-setup] [iSCSI support] allow selecting more than one iSCSI target
You can connect to more than one iSCSI target if you connect all the portals of an iSCSI portal group to enable multipathing before running the self-hosted engine deployment script. To be as backwards-compatible as possible and to avoid requiring changes in the deployment script, it saves the multiple IP and port values as a string composed of multiple comma-separated values with the same key used by the previous version. It assumes that the login is the same for all the portals.
BZ 1461251 [bug] hosted-engine yum repo required, but rpm-based install optional
Feature:
Provide path to Appliance OVF

Reason:
This feature is supported according to RedHat customer portal, but dropped in the past for some reason

Result:
User can provide path to appliance OVA instead of installing appliance RPM
BZ 1429537 [RFE] Rebase on gluster-3.12
Self-hosted engines now require GlusterFS 3.10 instead of 3.8.
BZ 1304650 [RFE] - he-setup should wait for all services and the Engine VM to come up successful at the end of the setup
With this release, the self-hosted engine deployment script waits for the Manager VM to power up before reporting that the deployment is complete. Now when the deployment is finished, you can connect to the Manager right away instead of waiting for the VM to power up.
BZ 1233127 [RFE] Warn when bad bond modes are used for the bond which is used for the initial VM network

oVirt Log Collector

BZ 1490447 [RFE] option to collect logs from one host per cluster
Feature:
Introduce hypervisor-per-cluster option, to collect data from a single hypervisor per cluster. If the SPM found in the cluster, collect data from it.

Reason:
Simplifies collecting data.

Result:
Data is collected from a single host per cluster.
BZ 1413316 [RFE] enable collectd plugin for sos reports when it will be available
When sos >= 3.4 is used, log-collector now also enables collectd plugin which collects the CollectD configuration
BZ 1020790 [RFE] - add options to rhevm-log-collector to limit size of collected logs
The ovirt-log-collector can now limit the maximum size of logs collected in order to capture relevant logs only. The size of the logs may be extremely large in environments with large numbers of hosts or a large number of exceptions, so ovirt-log-collector can now arbitrarily limit the size of logs collected, defaulting to the last day only.
BZ 1404509 [RFE] Log collector should collect time diff for all hosts
When collecting SOS reports from hosts, chrony and systemd SOS plugins can now collect information about time synchronization. In addition, a new –time-only option has been added to ovirt-log-collector, allowing information about time differences to be gathered from the hosts without gathering full SOS reports, saving a considerable amount of time for the operation.
BZ 1023455 [CodeChange][RFE] log-collector should use the same code used by the engine for parsing configuration

oVirt Provider OVN

BZ 1505398 OVS 2.6 obscures OVS 2.7 due to misuse of the epoch
This ensures that openvswitch version 1:2.6.1 (version: 2.6.1 epoch:1) is not consumed when the provider is installed. Ovs package 1:2.6.1 is a beta package which should not be used (but has accidentally been in the repos).

When ovs is not installed, the result will be that the correct version (if available) will be installed.

If 1:2.6.1 is already installed, the install operation will fail with the message: “… conflicts with openvswitch = 1:2.6.1 …”.
Manual action will be needed to replace the package. The user will have to manually change the openvswitch packages to the latest available.
The improper package version can be replaced by downloading and replacing the openvswitch packages with a specific version of openvswitch:

- download each of the openvswitch packages:
- provider: openvswitch, openvswitch-ovn-common, openvswitch-ovn-central, python-openvswitch
- driver: openvswitch, openvswitch-ovn-common, openvswitch-ovn-host, python-openvswitch
yumdownloader <package>-<version>
for example: yumdownloader openvswitch-2.7.2

- install the new version using the downloaded rpm files
yum downgrade <package>
for example:
yum downgrade openvswitch-2.7.2-10.git20170914.el7fdp.x86_64.rpm
BZ 1472747 Error while trying to authenticate ovirt-provider-ovn against Active Directory
Feature:
to authenticate ovirt-provider-ovn against an ldap server via user/password set

ovirt-admin-user-name=<admin_username>
in /etc/ovirt-provider-ovn/conf.d

and use <admin_username>@<ad_domain>@<auth_profile> when defining the external provider in ovirt-engine.

Similarly, to authenticate with an active directory group set in /etc/ovirt-provider-ovn/conf.d :

[AUTH]
auth-plugin=auth.plugins.ovirt:AuthorizationByGroup

and use <admin_username>@<ad_domain>@<auth_profile> when defining the external provider in ovirt-engine.

Reason:

Result:

oVirt Engine Appliance

BZ 1418579 Use selinux when building ovirt-appliance
Feature:
Set SELinux to enforcing in ovirt-appliance

Reason:
Enhance security for the ovirt-appliance

Result:
SELinux is now being enforced
BZ 1463853 [RFE] RHV-M appliance should meet NIST 800-53 partitioning requirements
Previously, the partitioning scheme for the RHV-M Virtual Appliance included two primary partitions, “/” and swap.

In this release, the disk partitioning scheme has been modified to match the scheme specified by NIST. The updated disk partitions are as follows:

/boot 1G (primary)
/home 1G (lvm)
/tmp 2G (lvm)
/var 20G (lvm)
/var/log 10G (lvm)
/var/log/audit 1G (lvm)
swap 8G (lvm)
/ 6G (primary)
BZ 1422982 [RFE] add swap to rhevm-appliance
Previously, the default memory allotment for the RHV-M Virtual Appliance was always large enough to include support for user additions.

In this release, the RHV-M Virtual Appliance includes a swap partition that enables the memory to be increased when required.

oVirt Guest Agent

BZ 1443143 Do not set tuned profile - leave whatever the guest has

oVirt Release Package

BZ 1429541 Rebase on Gluster 3.12
oVirt release now enables CentOS Storage SIG Gluster 3.10 repository. See Gluster 3.10 release notes for more information at https://gluster.readthedocs.io/en/latest/release-notes/3.10.0/

Deprecated Functionality

oVirt Engine

BZ 1456558 iptables support deprecation
With this update, iptables has been deprecated in favor of firewalld. In Red Hat Virtualization 4.2 it is still possible to use iptables but iptables will not be supported in future releases.
BZ 1443989 [RFE] Deprecate and remove spice-html5 support
The spice-html5 has been removed.
BZ 1473182 Drop ovirt-engine-setup-plugin-dockerc
With this update, the ovirt-engine-setup-plugin-dockerc package has been dropped. The ovirt-engine-setup-plugin-dockerc package was previously deprecated in version 4.1.5.

oVirt Host Deploy

BZ 1426580 Remove qemu-kvm-tools installation
With this update, the Host Deploy is no longer installing qemu-kvm-tools on deployed hosts.

Known Issue

imgbased

BZ 1454536 HostedEngine setup fails if RHV-H timezone < UTC set during installation
Currently, the Red Hat Virtualization Host generates VDSM certificates at the time of the first boot. This means that if the system clock was not set correctly at install time then chrony or ntpd may resynchronize the clock after the VDSM certificate was generated, leading to a certificate that is not valid yet if the appropriate timezone is behind UTC. A workaround for this is to set the system clock appropriately at install time. Now, imgbased-configure-vdsm starts after chronyd or ntpd and waits two seconds for the clock to synchronize, but this is not a guarantee.

Cause:
Testing completion of a live merge operation was incorrect, checking live merge progress value available via libvirt api which does not provide the status of a live merge operation.

Consequence:
Live merge was detected as completed before the operation was actually completed. Trying to finalize the merge operation failed repeatedly until the operation was actually completed, logging multiple errors during the process.

Fix:
Detect live merge completion using the libvirt xml.

Result:
Live merge operation will complete successfully without logging errors.

BZ 1504265 [UI] engine errata grid missing links to detail view
BZ 1380498 [RFE] host upgrade should upgrade the whole host, not specific packages
Up until version 4.2 the upgrade process of the host upgraded just few packages on the host relevant for the virtualization. The packages was be specified by following variables: PackageNamesForCheckUpdate, UserPackageNamesForCheckUpdate and OvirtNodePackageNamesForCheckUpdate.

Since version 4.2 the upgrade process of the host will update all packages, not only relevant one. We also added an option to choose whether the host should be rebooted after the upgrade is done, where the default option is to do a reboot.

Users can’t no longer choose relevant packages to check the upgrade, and so following config options don’t exists anymore:
- PackageNamesForCheckUpdate
- UserPackageNamesForCheckUpdate
- OvirtNodePackageNamesForCheckUpdate
BZ 1504005 Cluster can be created with empty ‘Default network provided’, which is causing NPE during host deploy
BZ 1467928 Shutdown of a vm during snapshot deletion renders the disk invalid
Cause:
Live merge failed during Merge Status command, Destroy Image command or Destroy Image Check command.

Consequence:
If this is an active image live merge, the top volume is left as illegal at the end of the failed live merge.

Fix:
The reason of the failure in those commands is, usually, network timeout when executing Vdsm verbs. In that case, we keep trying executing the verbs until succeeding.

Result:
Live merge process will not fail if there is an issue calling Vdsm and the top volume will not be illegal.
