[ovirt-users] After Upgrade OVirt 4.4.9 > Version 4.4.10.7-1.el8 VM Kernel Crashes after migration

19 Jan 2023

      Dear List,

we upgraded our OVirt 4.4.9 Infrastructure (engine and hosts) to latest 
available 4.4.10.x. Engine shows "4.4.10.7-1.el8" on Login Page

Hosts are based on ovirt-node-ng (nodectl info outputs 
ovirt-node-ng-4.4.10.2-0.20220303.0)

When we migrate VM's we see VM's dying short after migration with below 
errors also printed to console. We are only able to shutdown these VM's 
(PowerOff) and start them up again. Mostly they are started again on the 
Host that was target of migration and they run without issues then.

All Servers are EPYC based, but different CPU Versions. All hosts are in 
a single "Cluster", CPU Type is "Secure AMD EPYC". With 4.4.8 and 4.4.9 
we had no problems migrating VM's between hosts.

Cluster is:

2 Hosts: AMD EPYC 7401P 24-Core Processor
1 Hosts: AMD EPYC 7402P 24-Core Processor
7 Hosts: AMD EPYC 7502P 32-Core Processor

What can we do ? As said, we didn't see such problems for 1 year running 
4.4.8.x and 4.4.9.x.
