I find the rules， it no matter with windows 2012, it depend on video type,
if type is cirrus, or use nvidia GPU in display settings, will cause this
problem:
<video>
<model type='cirrus' vram='16384' heads='1' primary='yes'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</video>

Code is STATUS_INVALID_PARAMETER.
I don't see any reason (beside from device_name) for this result but
looks like a bug indeed.
