Hi, i'm experiencing reproducible problems migrating Windows 2012R2 VMs in oVirt 4.1 environments. I can't migrate two different Windows 2012R2 VMs in two different oVirt environments. engine.log in this situation is the same in both cases, i'm attaching it. lines like "Failed to destroy VM 'd4ddd4d1-2de4-4ace-900d-76552cadefb0' because VM does not exist, ignoring" "VM 'd4ddd4d1-2de4-4ace-900d-76552cadefb0'(ovirt-test03_win2012) was unexpectedly detected as 'Down' on VDS 'xxx'" don't sound too confidence-inspiring. Windows 2008 and Windows 2016 VMs can be migrated with no problem. - oVirt version is 4.1.6 - VirtIO drivers and oVirt guest agent in windows guest were installed from oVirt-toolsSetup-4.1-5.fc24.iso (one VM is using VirtIO devices, other VM isn't) - oVirt cluster migration settings are default in a 4.1 install (migration policy: legacy, i also tried: minimal downtime, post copy migration, no avail...) thx for any advice matthias
