Hi everyone, The recent release of Stream for Ubuntu made me consider a "gaming Ubuntu" domU. I would prefer gaming on GNU/Linux mainly to show my support towards "Steam for Linux". I''ve got one domU, a HVM Windows 7, I use it for gaming only. I passed my HD6850 to it and it works perfectly. I had a hard time configuring it but in the end I''m very satisfied with it. I supposed I could make an Ubuntu install. I read that GNU/Linux can run in PV mode for better performance but as I understand PV machines can''t accept PCI passthrough. So I decided I''ll use Xen HVM. First I tried Xubuntu 12.10 (I don''t like Unity that much). It recognized that it was running on Xen HVM but I couldn''t log in after the install. Never mind, I tried Xubuntu 12.04.2. I installed it and it looked fine without passthrough. But I couldn''t managed to pass my PCI cards and video card to it. I tried it one by one, all together, with or without gfx_passthru=1 I even tried installing it with a full config file, all stuff passed to if from the very beginning. All I got when I tried to pass my graphics card was a black screen. The Windows domU works perfectly, so my system is capable of passing trough the VGA. Is there any tutorials for this stuff? I tried to Google it but I couldn''t find anything. Can it be the AMD video driver for Ubuntu is missing? I''m using the HDMI output of my card. Isn''t Ubuntu supposed to use a general VESA driver in this case? Am I missing something trivial?
