[ovirt-users] Re: Windows VMs randomly wont boot after compatibility change

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).
