[Spice-devel] windows server 2012： WDDMInterface::escape::this should never happen. Status is 0xc000000d

[franklin zhou]

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.
