Hey,
This is noted in the documents:
https://www.ovirt.org/documentation/upgrade_guide/index.html#Changing_the...
I recommend if you can't cope with it (i.e: logging to console and
reconfiguring the NICs/Disks) it to change the VM custom emulated machine
to "pc-q35-rhel8.1.0", this is the default emulated machine when cluster
compatibility level is set to 4.4.
Also note, if you heavily rely on VNC, there's a bug introduced in libvirt
8 that won't allow to set password length longer than 8 chars, oVirt by
default tries to set a password length of 12 chars but up until now libvirt
simply ignored that and set the password based on the first 8 chars, i
don't know from which version that happened but in 4.4.10 you won't be able
to use VNC so i recommend to use SPICE (which is actually much better).

Hello,
I have noticed that some of our Windows VM's (2012 - 2022) randomly won't
boot when reboot is initiated from guest OS. As far as I can tell this
started happening after we raised the cluster compatibility from 4.4 to 4.5
(it's 4.6 now). To fix it a VM needs to be stopped and started.
We are running oVirt 4.4.10.
I cannot really see much from the logs if grepping for a specific VM that
had these issues.
Example VM ID is: daf33e97-a76f-4b82-b4f2-20fa4891c88b
Im attaching logs:
- Initial hypervisor where VM was running on (reboot is initiated at
4:06:38 AM): vdsm-1.log
- Second hypervisor where VM was started after it was stopped and started
back (this was done 7:45:43 AM): vdsm-2.log
- Engine log: engine.log
Has someone noticed any similar issues and can provide some feedback /
help?
Regards,
David
