hi there, I wanted to share some fairly good newsa while ago when as was battling the problem - pci-assign a vga - I got it to work
I realized that it might have worked from the beginning, anyhow,for me it works now with qemu-kvm 1.2 (which is fedora alpha rpm-rebuilt on SL 6.3) with various AMD vgas
but! (there is always a but, isn't there :) )guest loses vnc?? meaning that VNC gets only blank(black screen (this was what deceived me earlier)) whereas guest seems to fine itself, I can rdp to it (it's win7), I can get it on a directly attached monitor via keyboard + mouse attached in the same fashion only win device manager shows "Standard VGA Graphic Adapter" exclamation marked. (I tied both -vga cirrus and -vga std)
would anybody know how to fix/troubleshoot it? many thanks On 03/10/12 15:46, Alex Williamson wrote:

We've had a couple reports of some cards working, but nothing worth declaring success, backporting and trying to call it supported. If a seabios update improves things for you, please report it and maybe there are changes we can backport. Personally I'd prefer to see it working reliably upstream first and incorporate a full solution rather than hearsay that card A worked on system B at least once. Thanks, Alex
