oVirt 4.4.1.4 Release Notes

The oVirt Project is pleased to announce the availability of the 4.4.1.4 release as of July 28, 2020.

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 8.2 and CentOS Linux 8.2 (or similar).

To find out how to interact with oVirt developers and users and ask questions, visit our community page. All issues or bugs should be reported via Red Hat Bugzilla.

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 4.4.1, see the release notes for previous versions.

oVirt 4.4.1.4 Release Notes
1. What’s New in 4.4.1?

What’s New in 4.4.1?

Release Note

oVirt Release Package

BZ 1844389 CentOS Stream release rpm

CentOS Stream can now be used as an alternative to CentOS Linux on non production systems.

oVirt Engine

BZ 1838159 [RFE] Upgrade apache-sshd to 2.5.0 to allow RSA-SHA256 and RSA-SHA512 public keys

It’s possible to add hosts, which don’t provide classic rsa-sha-1 SSH public keys, but provide only rsa-sha256/rsa-sha-512 SSH public keys (for example CentOS 8 hosts with FIPS hardening enabled), to oVirt Engine.

Enhancements

oVirt Engine

BZ 1813831 [RFE][CBT] Allow to view and remove VM backup checkpoints

Feature:

Incremental backup root checkpoint removal.

Reason:

Before this feature, when a backup was taken for a VM a checkpoint created in libvirt and on the engine database.

In a large scale scenario, users can have many backups for a VM so there will be many checkpoints on libvirt and on the engine database. This could lead to performance degradation when the engine needs to redefine the checkpoints on the host after the VM powered off and restarted, also, saving many checkpoints in the database will consume a lot of space because each checkpoint entity saves the created checkpoint XML description.

Result:

This feature provides the following operations -

View all the VM checkpoints using the new checkpoints service under the VM service -

GET path-to-engine/api/vms/vm-uuid/checkpoints

View a specific checkpoint -

GET path-to-engine/api/vms/vm-uuid/checkpoints/checkpoint-uuid

Remove the oldest (root) checkpoint from the chain -

DELETE path-to-engine/api/vms/vm-uuid/checkpoints/checkpoint-uuid

BZ 1477049 [RFE] [New UI - New setup networks dialog] - Add ‘Unmanaged’ network icon to the front NIC panel

Feature: In the NIC list dialog of the host, indicate on each NIC whether one of its networks is unmanaged by oVirt engine.

Reason: To view this indication the user had to open the setup dialog which is cumbersome.

Result: unmanaged networks are viewable by the user on the host NICs page at a glance.

BZ 1806339 In Admin Portal, “Huge Pages (size: amount)” needs to be clarified

Feature: Changed the Huge Pages label to say Free Huge Pages

Reason: For more clarity so that the user can understand the values.

Result: The functionality is more user friendly.

BZ 1763812 [RFE] Move the Remove VM button to the drop down menu when viewing details such as snapshots

Feature: Moved the VM remove button to the more button’s drop down menu.

Reason: For usability. Many users would press the remove VM in a details tab view thinking that it would just remove the detailed item. Instead it deleted the VM itself.

Result: The user now has to press the more drop down button to delete the VM, but it should be less confusing as to which button to use when attempting to remove a detail such as a snapshot.

BZ 1768937 [RFE] [UI] Copy host networking from one host to another

Feature: Provide a means of invoking the copy host networks functionality from the web-admin portal. A button to invoke the action was added to the all hosts and single host pages.

Reason: This functionality should be available from the web-admin as all othe oVirt-engine functionality.

Result: User can invoke a copy host networks action from the web-admin.

BZ 1841083 bump up max memory limit to 6TB

With this update, the maximum memory size for 64-bit virtual machines based on x86_64 or ppc64/ppc64le architectures is now 6 TB. This limit also applies to virtual machines based on x86_64 architecture in 4.2 and 4.3 Cluster Levels.
BZ 1679730 Warn about host IP addresses outside range

Feature:

Add audit log warning on an out of range IPv4 gateway static configuration for a host NIC. The validity of the gateway is assessed compared to the configured IP address and netmask.

Reason: A bad configuration is sometimes difficult to detect and may go unnoticed.

Result: Better feedback to the user

oVirt Engine Data Warehouse

BZ 1848381 [RFE] Add description panel to all oVirt dashboards

Feature: Description panels

Reason: Explain to the user what reports are presented and what their purpose is.

Result: Text that explains the reports, on each dashboard and at the beginning of the page

oVirt Engine WildFly

BZ 1830951 Rebase on Wildfly 19.1

With this release, the oVirt engine runs on WildFly 19.1.0.Final.

oVirt Ansible hosted-engine setup role

BZ 1828888 Copy disk task risky and not optimal
BZ 1828892 Add qemu-img compare task to verify disk copy

Feature: Add compare task in debug mode to verify that image copied successfully to the storage domain

Reason: To verify the image copied successfully

Result: Task should succeed if the copy of the image succeeds

oVirt Engine UI Extensions

BZ 1768937 [RFE] [UI] Copy host networking from one host to another

Feature: Provide a means of invoking the copy host networks functionality from the web-admin portal. A button to invoke the action was added to the all hosts and single host pages.

Reason: This functionality should be available from the web-admin as all othe oVirt-engine functionality.

Result: User can invoke a copy host networks action from the web-admin.

Known Issue

oVirt Engine Data Warehouse

BZ 1846256 SSO allows all engine users to login to grafana

Grafana now allows Single-Sign-On (SSO) using oVirt engine users, but does not allow automatic creation of them. A future version (see bugs 1835163 and 1807323) will allow automatic creation of admin users. For now, users must be created manually, but after that they can login using SSO.
