Comment 8 for bug 1966499

Similar configuration with Windows guests (6 total):

root@cluster-05:/var/log# virsh dumpxml guest1 |grep -A 4 '<video>'
    <video>
      <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
    </video>

This is the first error, just after starting the first vm.
