Re: VGA Passthrough (NVIDIA) - current status?
[In reply to]
Apart from their high end workstation cards, such as the Quadro 2000,
Nvidia cards aren't known to be Xen friendly. On the other hand, even
mid-range AMD Radeon cards have been reported to support VGA-passthrough.
(See http://wiki.xen.org/wiki/XenVGAPassthroughTestedAdapters) So to save
yourself many headaches, I recommend that you invest in a mid-range (or
better) AMD Radeon card. In my case, I found that a GigaByte AMD Radeon HD
6670 (about $60 on sale) supported VGA-passthrough with an HVM domU.
For a well-written and very detailed tutorial describing something similar
to what are describing, have a look here:
