Previously, chipsets and emulated machines were not part of the cluster update. The current release fixes this issue.

Description Kobi Hakimi 2020-06-16 14:21:08 UTC

Description of problem:
[UPGRADE] failed to change the cluster compatibility version from 4.3 > 4.4 while VMs running on the cluster.

Version-Release number of selected component (if applicable):
ovirt-engine-4.3.10.3-0.2.el7.noarch
ovirt-engine-4.4.1.2-0.10.el8ev.noarch

How reproducible:
100%

Steps to Reproduce:
Upgrade from 4.3 to 4.4(this case is related to hosted engine environment):
1. Backup the engine in 4.3 to file.
2. Provision the first host.
3. Deploy the hosted engine 4.4 by restore from the backup file.
4. Upgrade the hosts one by one. (by maintenance > remove from engine > provision to rhel-8.2 > Add them back to engine).
5. Update the compatibility version of the Clusters from 4.3 to 4.4

Actual results:
when the cluster has running VM's we got the following error:

"""
Error while executing action: Update of cluster compatibility version failed because there are VMs/Templates [golden_env_mixed_virtio_3_1, golden_env_mixed_virtio_3_0, golden_env_mixed_virtio_1_0, HostedEngine, golden_env_mixed_virtio_2_0, golden_env_mixed_virtio_2_1, golden_env_mixed_virtio_1_1] with incorrect configuration. To fix the issue, please go to each of them, edit, change the Custom Compatibility Version of the VM/Template to the cluster level you want to update the cluster to and press OK. If the save does not pass, fix the dialog validation. After successful cluster update, you can revert your Custom Compatibility Version change.

"""

Expected results:
to be able to upgrade the cluster from previous version to the latest version without downtime of the VMs.
