Hi Arsene, i have to apologize, your hint to the QXL driver was right. after searching in the wrong places for most of the time i finally looked into the logs of the hypervisor host and found libvirtError: internal error: unable to execute QEMU command 'migrate': qxl: guest bug: command not in ram bar which led me to https://bugzilla.redhat.com/show_bug.cgi?id=1446147 you can't use https://www.spice-space.org/download/windows/qxl-wddm-dod/qxl-wddm-dod-0.18/ in windows 2012, but when uninstalling the Red Hat QXL driver completely the VM is finally able to migrate thanks matthias Am 2017-11-08 um 10:38 schrieb Matthias Leopold:
Hi Arsene,
thanks for your feedback. I doubt that a display device driver in the guest can be responsible for the mentioned migration problems in the virtualization environment. Nevertheless i installed https://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-t... im my Windows 2012R2 VM (the driver in your link didn't install). As i expected this didn't fix the migration problem.

Hi Mathias,
I had a similar problem with Windows Server 2016 and could resolve it by installing the latest driver for QXL found at https://www.spice-space.org/download/windows/qxl-wddm-dod/qxl-wddm-dod-0.18/. This should also work for Windows 2012R2.

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
