RHBA-2022:0461 - Bug Fix Advisory

Topic

Updated ovirt-engine packages that fix several bugs and add various enhancements are now available.

Description

The ovirt-engine package provides the manager for virtualization environments.
This manager enables admins to define hosts and networks, as well as to add
storage, create VMs and manage user permissions.

Changes to the libvirt component:

• Previously, the default disk configuration did not propagate disk errors to the client, which caused the virtual machine to stop. As a result, the Windows high availability cluster validator failed and one of the virtual machines in the cluster was paused. In this release, disk errors are propagated to the client using the "engine-config -s PropagateDiskErrors=true" setting. The Windows high availability cluster validator works and all tests, including iSCSI reservations, have passed. (BZ#1898049)

Changes to the ovirt-engine component:

• Previously, when unassigning a storage connection from a storage domain for a LUN associated with another storage server connection, all storage connections for that LUN were removed and the LUN was also removed.

In this release, only the specified storage connection is removed. The LUN is removed only if it has no storage connections. (BZ#2022660)

• Previously, RHEL 7 hosts could not be added to the Red Hat Virtualization Manager in clusters with level 4.3 or 4.2.

In this release, RHEL 7 hosts can be added to the Red Hat Virtualization Manager successfully in clusters with level 4.3 or 4.2. For additional details, see BZ#2019807. (BZ#2032919)

• In this release, monitoring of host refresh capabilities functionality was improved to help debug very rare production issues that sometimes caused the Red Hat Virtualization Manager to lose connectivity with the Red Hat Virtualization hosts. (BZ#1897114)
• Previously, a non-responding host was first soft-fenced by the Engine, but this did not fix the connectivity issue. The engine did not initiate a hard fence and the host was left in an non-responding state.

In this release, soft fencing has been fixed so that if the soft fencing does not make the host responsive again, then the non-responding host treatment process continues correctly with the additional steps. (BZ#2007286)

• Previously, certain CPU topologies caused virtual machines with PCI host devices to fail. In this release, the issue has been fixed. (BZ#2025872)

Changes to the ovirt-engine-dwh component:

• Previously, the VM memory/CPU overcommit panels in the Ovirt Executive Dashboard/Cluster Dashboard displayed the average memory for a single hypervisor and the average memory of all virtual machines in a cluster.

In this release, the dashboard panels show the correct overcommit rates between all the hosts in the cluster and all the virtual machines in the cluster. (BZ#2014882)

Changes to the ovirt-engine-metrics component:

• Previously, ELK integration failed due to missing configuration parameters when using certificates.

In this release, the missing parameters were added, and updated to the correct names according to the logging role. ELK integration now works with or without certificates. (BZ#1978655)
