I recently added a Windows 10 Pro 64 bit (release 1909) VM, and I'm seeing a lot of failures when oVirt tries to move the VM to another host (triggered by load balancing),

These errors are showing up in the UI event log

Migration failed  (VM: <vm label>, Source: <host 1>, Destination: <host 2>).

Followed by:

VM <host> is down with error. Exit message: Lost connection with qemu process.

Google returned some references to 'options kvm ignore_msrs=1' which I've added to /etc/modprobe/d/kvm.conf and restarted the hosts but that doesn't appear to have made a difference.

Is this a known issue with Windows 10 guests?
