Hi, Is there anything that I should take note of for gfx passthrough in the latest Xen unstable? I followed mostly the instructions from http://wiki.xensource.com/xenwiki/VTdHowTo. I tried doing pciback.hide on 01:00.0 (gfx), and was able to see it in /sys/bus/pci/drivers/pciback. "dmesg | grep pci" also showed the device being seized. I would have expected that I won''t be able to see anything on my screen, which wasn''t the case (I did notice losing the screen in an earlier version of Xen unstable). I tried to assign the device to DomU by "pci=[''01:00.0'']". But lspci wasn''t able to see the device in DomU. However, when I shutdown DomU, my screen went blank. My serial connection and ssh is still up though. Somehow, I think this isn''t the expected behavior, or am I wrong? Btw, I''m using a Intel DQ45CB and HD2600XT. I''ve explicitly selected PCIe card in the BIOS. This is my lspci. 00:00.0 Host bridge: Intel Corporation Unknown device 2e10 (rev 03) 00:01.0 PCI bridge: Intel Corporation Unknown device 2e11 (rev 03) 00:03.0 Communication controller: Intel Corporation Unknown device 2e14 (rev 03) 00:03.2 IDE interface: Intel Corporation Unknown device 2e16 (rev 03) 00:03.3 Serial controller: Intel Corporation Unknown device 2e17 (rev 03) 00:19.0 Ethernet controller: Intel Corporation Unknown device 10de (rev 02) 00:1a.0 USB Controller: Intel Corporation Unknown device 3a67 (rev 02) 00:1a.1 USB Controller: Intel Corporation Unknown device 3a68 (rev 02) 00:1a.2 USB Controller: Intel Corporation Unknown device 3a69 (rev 02) 00:1a.7 USB Controller: Intel Corporation Unknown device 3a6c (rev 02) 00:1b.0 Audio device: Intel Corporation Unknown device 3a6e (rev 02) 00:1d.0 USB Controller: Intel Corporation Unknown device 3a64 (rev 02) 00:1d.1 USB Controller: Intel Corporation Unknown device 3a65 (rev 02) 00:1d.2 USB Controller: Intel Corporation Unknown device 3a66 (rev 02) 00:1d.7 USB Controller: Intel Corporation Unknown device 3a6a (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a2) 00:1f.0 ISA bridge: Intel Corporation Unknown device 3a14 (rev 02) 00:1f.2 SATA controller: Intel Corporation Unknown device 3a02 (rev 02) 00:1f.3 SMBus: Intel Corporation Unknown device 3a60 (rev 02) 00:1f.5 IDE interface: Intel Corporation Unknown device 3a06 (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 9588 01:00.1 Audio device: ATI Technologies Inc Unknown device aa08 02:01.0 FireWire (IEEE 1394): Agere Systems FW323 (rev 70) Would appreciate any suggestions or comments.
