I know that this particular card could be hard-moded to GRID K2 so VGA passthrough could work. FYI, GTX680 modified to a K5000 also works fine for VGA passthrough. I haven't noticed any difference in the functionality. Following instructions found on http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/420/ I just removed two resistors. Just out of interest - are your video outputs working correctly? Can you get DL-DVI output or DP output without problems? I find that on bare metal, it works fine, but in a Xen VM, SL-DVI works, but DL-DVI doesn't. DP also works on bare metal, but doesn't work at all domU. As far as I can tell, nobody has had the same issue before. Then again, AFAIK, nobody else is running this setup with an XP64 domU, which is why I am particularly interested to hear if you are seeing the same issue (you mentioned you also run XP64). I did the test on another VM (Windows 7 64 bits). I was able to play games, shutdown the VM, restart the VM without restarting the dom0. I am very impressed. Restarting domU (Linux or Windows) without restarting the dom0 is very impressive. Indeed. As I have mentioned a number of times before, a faux-Quadro setup is far, far superior to an ATI setup when it comes to VGA passthrough. And I wouldn't say it's impressive per se - it is normal and expected. OTOH, having to reboot dom0 when rebooting domU is utterly broken and unfit for purpose.
