My motherboard is the "Z68 Extreme7 Gen3", and it supports VT-d. I also have an i3, that also supports VT-d.

I would like to play games under a virtualized environment using graphics card passthrough. What Hypervisor and GPU support this?

Is this even possible?

Probably, Xen - take a look at this Phoronix post – Sathya Jul 27 '12 at 10:55
Keep in mind, you can't passthrough a device if the VM host is using it. You'll probably need a separate graphics card for the host. – Wyzard Jul 27 '12 at 12:09
Thanks both. I've purchased a 7970 and i will post the results :) – cedivad Jul 27 '12 at 18:54

Well, it was rather easy to make it work.

Ubuntu 12.04 + Xen 4.1
ASRock Z68 Extreme7 Gen3
Intel i5-2500 (not the K version)
AMD 7970 Gh Edition

enter image description here

ATI seems to be the only viable solution while Xen-dev 4.2 is working on something for Nvidia, but they are still in alpha stage. They implement a pack that makes Nvidia cards working a little bit and they break AMD support. Tragicomic.

How does this work in practice? Can you switch between Ubuntu and Windows? Are they using the same graphics card and monitors? – Oli Mar 26 '13 at 15:44
Ubuntu is the hypervisor and dosen't have a graphic device. It's a server on the rooftop. For do what you want to, you should use the (mainboard) gpu for ubuntu, and the radeon for windows. – cedivad Mar 28 '13 at 9:50
@cedivad: I have one doubt is the graphics card also virtual in your experiment? – karthick Jul 17 '13 at 13:30
No, it's real, in every sense. – cedivad Jul 26 '13 at 10:12
