Dear David Techer, I noticed that there are FOUR memory ranges for the VGA card to be passed through. lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 8400 GS] (rev a2) dmesg | grep 01:00.0 | grep "pci.*mem" [0.120488] pci 0000:01:00.0: reg 10: [mem 0xd2000000-0xd2ffffff] [0.120508] pci 0000:01:00.0: reg 14: [mem 0xc0000000-0xcfffffff 64bit pref] [0.120528] pci 0000:01:00.0: reg 1c: [mem 0xd0000000-0xd1ffffff 64bit pref] [0.120556] pci 0000:01:00.0: reg 30: [mem 0xd3000000-0xd307ffff pref] _*Why do you use only the first three memory ranges?*_ How about the last (i.e. the fourth) memory range? Is there a mistake in your method or blog? This is because I have realized now that my Xen VGA Passthrough is only partially successful. I can run 2D graphics benchmarks, but NOT 3D graphics benchmarks. Please check out my Youtube video. Device Manager says that Windows 8 and XP has stopped the VGA card because it has a problem. Device manager also says that the VGA card is not using any resources because it has a problem. There is a yellow exclamation mark besides NVIDIA Geforce 8400 GS. Thank you very much.
