Hi, I'm trying to pass an intel video card to a guest via VT-D. I got this to work once so i know my system can do it, but I can't seem to replicate my success. Not sure if something changed in the bios(vt-d is still enabled there), or elsewhere. When I pass a device with gfx_passthru=0 (using config below), guest boots up and the vid card shows up at an incorrect pci id(ie not 00:02.0). Things work as expected. When I set gfx_passthru=1, the monitor goes blank, and after 12 seconds of execution, I get a vague 'Error: Device model isn't ready for commands' when running the xm create command. Please hint on where things are failing. Thanks, Taras I get this error with xen 4.1 on 3.2 and 4.2 on 3.7.
