oVirt 4.2.2 Release Notes

The oVirt Project is pleased to announce the availability of the 4.2.2 release as of March 28, 2018.

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.

To learn about features introduced before 4.2.2, 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.

oVirt 4.2.2 Release Notes

What’s New in 4.2.2?

Enhancements

oVirt Log Collector

BZ 1540219 detect last backup in analyzer report

oVirt Hosted Engine Setup

BZ 1479714 [RFE] - HE should support Gluster replica 1 or 3.
Feature: Support running HE on a replica 1 gluster volume

Reason: This will enable single node hyperconverged deployments.
BZ 1542604 [RFE] HE setup: Ansible Flow: Show only active network interfaces for setting ovirtmgmt bridge
Ansible Flow: Show only active network interfaces for setting ovirtmgmt bridge

oVirt Engine

BZ 1539636 [RFE] Support configuring lvmcache during brick creation
Feature: Support configuring lvmcache on thinpool used for gluster bricks

Reason: SSD devices on the servers provide better I/O performance and can be leveraged to deliver performance improvement for gluster volumes when the bricks are comprised of slower HDDs.
BZ 1528371 engine-setup fails to upgrade postgres from 9.2 to 9.5 if the system wide locale differs from system wide locale at first installation time
engine-setup can now successfully upgrade PostgreSQL from 9.2 to 9.5 also when the locale of the 9.2 database is different from the system locale.
BZ 1150245 [RFE] Add facility to move a memory volume
Moving memory disks (disks that are part from a live snapshot with memory or hibernation) can now be moved to other storage domains within the same data center
BZ 1542118 [downstream clone - 4.2.2] [RFE] Add facility to move a memory volume
BZ 1540289 Very slow login to and very slow execution in the RHV Manager
We are now exposing ENGINE_JBOSS_BLOCKING_TIMEOUT option, which can be used to change default value of jboss.as.management.blocking.timeout JBoss option.

To change the default administrators need to create /etc/ovirt-engine/engine.conf.d/99-jboss-blocking-timeout.conf with following content:

ENGINE_JBOSS_BLOCKING_TIMEOUT=NNN

where NNN is the number of seconds for this JBoss timeout.
BZ 1379309 [RFE] Integrate with gluster eventing
Feature: Integrate oVirt with gluster events framework

Reason: Push based monitoring rathen than frequent polling from engine to determine status of gluster volume entities
BZ 1515308 [RFE] [HC] Disable unrelated gluster hooks during host deploy
Feature: For hyperconverged deployments, disable gluster hooks that are unrelated, for instance SMB and NFS hooks

Reason: Hook evaluation on gluster events can hamper performance, hence disabling hooks that are not relevant
BZ 1546668 [UI] Option to disable auto-sync per provider
Feature: Option to enable and disable auto-sync per provider

Reason: Was requested by users.

Result: The property ‘autoSync’ of a network provider can be set on creating a new provider and read and set during editing an existing provider.
BZ 1319524 [RFE] Allow downloading VM to named OVF/OVA to client or to nfs paths (even if VM has snapshots)
Feature:
Allow exporting VMs (it is no available for templates yet) to OVA files that are placed on a given path on one of the hosts in the data center.

Reason:
This feature introduces an alternative for export domains. Users can export VMs to any shared storage that is mounted to any of the hosts in the data center.

Result:
An OVA file is created in the given path on the selected host. That OVA is a portable file which can later be imported, e.g., to a different deployment of RHV.
BZ 1539363 [RFE] Add a mechanism for canceling an image download automatically when there’s no activity after a configurable timeout is reached
A new configuration value was introduced, TransferImageClientInactivityTimeoutInSeconds (default = 60 seconds).
When there’s no activity with an image transfer, the engine keeps monitoring the transfer for a period of time that equals to this configuration value, and then it stops the transfer.
In upload flows - the transfer is paused as it can be resumed. In download flows - the transfer is canceled as it cannot be resumed anyway.

Note that this configuration value is relevant for both transfer types (upload and download) and both clients (REST-API and webadmin).
Also, note that the old configuration value, UploadImageUiInactivityTimeoutInSeconds, was removed, as the new configuration value includes this specific case (upload via webadmin).
BZ 1520424 [RFE] Fence hosts which became NonResponsive right after engine startup
After starting up, the Manager will automatically attempt to fence unresponsive hosts that have power management enabled after the configurable quiet time (5 minutes by default) has elapsed. Previously the user needed to fence them manually.

VDSM

BZ 872530 [RFE][Tracker] - Wipe volumes using “blkdiscard” instead of “dd”
The default zeroing method has been changed from “dd” to “blkdiscard”.
The new default method performs significantly better than “dd” as it may use storage offloading if it’s supported by the storage array, and it consumes much less network bandwidth.
If required, it’s always possible to locally set back “dd” as the zeroing method by changing the “zero_method” parameter in /etc/vdsm/vdsm.conf to “dd”.
BZ 1555200 [RFE] Implement reset-brick usage on the gluster volume
BZ 1540548 [RFE] Automatically restart HA VMs paused due to I/O Error
Highly available VMs paused due to I/O error may be, depending on the VM settings in Engine, killed if they have been paused for too long. This happens only once the I/O error is gone and the VM is going to be resumed.

This change enhances the functionality and high availability by killing VMs with that Engine setting whenever they are paused for too long due to I/O error regardless whether and when they are going to be resumed.
BZ 1150245 [RFE] Add facility to move a memory volume
Moving memory disks (disks that are part from a live snapshot with memory or hibernation) can now be moved to other storage domains within the same data center
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 1475780 [RFE][scale] - Set “blkdiscard” as the default zero method
The default zeroing method has been changed from “dd” to “blkdiscard”.
The new default method performs significantly better than “dd” as it may use storage offloading if it’s supported by the storage array, and it consumes much less network bandwidth.
If required, it’s always possible to locally set back “dd” as the zeroing method by changing the “zero_method” parameter in /etc/vdsm/vdsm.conf to “dd”.

oVirt Engine Metrics

BZ 1545559 [RFE] Assign externalIP to the Elasticsearch Service
Feature:
Assign externalIP to the Elasticsearch Service.

Reason:
To automate this for the user so he will not need to do this manually.

Result:
Now this is configure during the ovirt metrics configuration script.
BZ 1520126 [RFE] Set curator configmap on metrics store machine
Feature:
Set curator configmap on metrics store machine

Reason:
To automate this for the user so he will not need to do this manually.

Result:
When running the configure metrics script, it configures the curator on the metrics store machine, for metrics index, the curation parameter and make it configurable.
BZ 1542973 [RFE] Add Viaq installation files to ovirt-engine-metrics repo
Feature:
Added a playbook that generates the vars.yaml file with the openshift_logging_mux_namespaces according to the ovirt_env_name the user configured and copies both vars.yaml and the ansible-inventory files to the metrics machine.

Reason:
This places the files required for the viaq logging installation on the metrics machine and already includes the openshift_logging_mux_namespaces.

Result:
This should simplify the oVirt metrics store installation.
BZ 1530919 [RFE]Include a vars directory instead of only single config.yml file and not hard code the path
Feature:
Include a vars directory instead of only single config.yml file and not hard code the path.

Reason:
Allow adding variable to a directory to be used in the for the ansible script.

Result:
User can now add variable file to /etc/config.yml.d/ and the will be used in the ansible playbook.

Known Issue

oVirt Engine

BZ 1554028 “No space left on device” error when copying a disk based on template to a block domain in DC <= 4.0 when the disk was extended
Cause:
qemu-img convert with compat=0.10 and a backing file writes
the space after the backing file as zeroes which may cause the output disk be larger than the LV created for it

Consequence:
Moving a disk that was extended and is based on a template disk will fail in storage domains older than V4.

Fix:
The move operation of such disks will be blocked with an error message instead of failing. The resolution for this scenario is to upgrade the DC to 4.1 compatibility version or newer.

Result:

until this fix, when a snapshot was previewed the VM lease was ignored.
Now if the snapshot or the VM contains a lease, it will be ignored.

1.VM snapshot and the active snapshot has a lease
on the same/different domain:
- while previewing:
use the active snapshot lease
- while undoing the preview:
revert to use the active snapshot lease
- while committing the preview:
use the lease that used in the preview

2.VM has a lease on the active snapshot but doesn’t have a
lease on the snapshot:
- while previewing:
no lease will be used in the preview
- while undoing the preview:
revert to use the active snapshot lease
- while committing the preview:
the active snapshot lease will be removed and the VM
will use the lease that used in the preview

4.VM doesn’t have a lease on the active snapshot but
does has a lease on the snapshot:
- while previewing:
new VM lease will create on the snapshot lease
domain
- while undoing the preview:
the created lease will be removed
- while committing the preview:
the VM will use the lease that used in the preview
