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

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-tools-latest.exe
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
