GPU passthrough to Linux guests using open source video drivers

GPU passthrough to Linux guests using proprietary drivers is spotty at best. For example, I can get GPU passthough working with an Ubuntu 12.04 HVM guest using one older Catalyst driver, but not with any newer drivers. Moreover, no matter what Catalyst driver I try, I have had absolutely no luck getting GPU passthough working with an Ubuntu 13.04 HVM guest.

Suggestion: Given the spotty nature of propriety drivers, I hope that the Xen Project will work closely with the developers of open source video drivers to enable GPU passthrough to Linux guests using open source drivers.

        So many people want this. When is it going to be looked at again? Tobias, the NVidia stuff only works on 32-bit dom0 apparently. It doesn't look like it'd get pulled into an mainline xen anytime soon.

        Don't the NVIDIA drivers accomplish this in the recent XenServer 6.2 release?
