Indeed nothing really evident from qemu log, as unfortunately was expected.

We heard about problems on qemu 0.12.x and recent windowses.
This bug may be relevant: https://bugzilla.redhat.com/show_bug.cgi?id=1163828

You are not facing the same issue but something underneath can be related.

I'd suggest you to disable the hyperV optimization and see if that
helps.

To do so, you need to edit the osinfo properties (should be in
/usr/share/ovirt-engine/conf/osinfo-defaults.properties
)

and change the line

os.windows_xp.devices.hyperv.enabled.value = true

to

os.windows_xp.devices.hyperv.enabled.value = false

After a restart of Engine, you'll need to reboot the affected VM to
let its configuration change.

To check that the configuration changed, you should NOT
see anymore this option

hv_relaxed

in the qemu commandline/logs

If this doesn't help, I'm afraid you'll need to file a QEMU bug.

HTH,
