Re: [Xen-users] VGA Passthrough with Linux guests

I have a radeon HD7950, and tried secondary GPU passthrough with ubuntu guest 12.10 and 13.04, and also with a ArchLinux guest, and it didn't work (no OpenGL, fglrxinfo segfault ...).

Aside from Windows 7 guests (which work great under XCP 1.6), I've only tried GPU passthrough with Ubuntu guests.  Under XCP 1.6, GPU passthrough seems to work pretty will with Ubuntu 12.04 as a guest when using a Radeon HD 6670 as a secondary card combined with whatever version of Catalyst (not the updates) that is in found Ubuntu 12.04 repositories.  (I haven't had any luck with any other version of Catalyst.) 

But as for Ubuntu 12.10, 13.04 and 13.10 guest, I've had no such luck with GPU passthrough, no matter what version of Catalyst I try.  Would enjoy learning if anyone else has had better luck with any of these newer versions of Ubuntu.

Thanks for the info, I will try with a 12.04 guest then.
