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

It's becoming possible to share a GPU between guest OSes on modern Intel Platforms (Haswell and later) using XenGT (Intel GVT-g).
For AMD, as I understand this, it's possible only for a limited number of dedicated server GPUs.

The Intel CPUs need integrated Iris pro for it to work though. – CMCDragonkai – 2015-10-08T09:10:47.523
@CMCDragonkai: Could you please prove that Iris Pro is needed? I see only the statement "support starting from 4th Generation Intel Core processors with Intel Graphics processors" (source). Therefore, as I understand it, other integrated GPUs (HD and Iris) should be supported also.

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.

2I don't think you'd get decent performance out of Hackintosh running Parallels. Hackintosh questions are off topic for Super User. – slhck – 2012-03-23T11:36:14.360
Ok, edited for more generality – Mischa Arefiev – 2012-03-23T11:43:51.933
Looks good, cheers! – slhck – 2012-03-23T11:47:12.803
