Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have a desktop PC (Athlon 64, 2 cores).

I want:

  • to run Windows (Vista most likely) with full 3D support for video games and Youtube,
  • to also run Debian GNU/Linux with 3D support for work,
  • maybe other OSes as well.

I don't think my CPU supports VT-x, but it should have AMD-V. So the question is: can all of this be done with Xen (Xen on bare metal, all OSes as guests) with 3D working everywhere?

I don't think you'd get decent performance out of Hackintosh running Parallels. Hackintosh questions are off topic for Super User. –  slhck Mar 23 '12 at 11:36

Looks good, cheers! –  slhck Mar 23 '12 at 11:47

The short answer is that yes, it s possible, but there are some caveats. In order to have each guest have 3D acceleration, you'll need to pass through a graphics card of some sort to each guest. This means that you either have to have GPU capable of being presented to multiple guests, a GPU for each guest, or only run as many guests concurrently as you have GPUs to support it. The GPUs that support multiple guests are generally pretty expensive - the nVidia Tesla series is one of them, and I believe starts around $1000 USD. Other, less expensive GPUs can also be used, but generally only support a single guest, and it is hit-or-miss as to whether they work with Xen.
