libvirt users - Jan 2018 - Re: Using Intel Quick-Sync with GPU capable Intel CPUs

Rogue S.T asked about checking out graphics cards which brought the question to
me...


Is it possible to make Intel on-CPU GPU resources to Windows 10?


(the box I'm working with has Xeon E5-2640v4 CPUs which should be QuickSync
capable)

What else do I have to do to take advantage of this?

Just load the drivers?

Thanks,

I've no idea what QuickSync is, but GPU assignment should would just fine.

And before that define <hostdev/> in the domain XML so that libvirt
enables the PCI assignment. For instance:

  00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530
(rev 06)

  <hostdev mode='subsystem' type='pci'
managed='yes'>
    <source>
      <address domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
    </source>
    <address type='pci' domain='0x0000' bus='0x00'
slot='0x04'
function='0x0'/>
  </hostdev>

It's what Intel calls their GPU on CPU 
"stuff"

OK -- I'll take a look - but I'm assuming adding that doesn't infer
I want to use the device for actual video. The display will still be the
SPICE/VNC/WHATEVER that the system thinks it's the official display now.
