Just to let you know, here are the specs for another successful VGA passthrough on Xen hypervisor 4.1.2:
i7 3930K C2 stepping
Asus Sabertooth X79 motherboard with 1203 BIOS
Sapphire (AMD) 6450 graphics card for domU on PCIe slot 1 (using proprietary AMD driver for Linux dom0)
PNY Quadro 2000 (Nvidia) graphics card passed through to Windows 7 Pro 64 bit
120GB SSD for Linux dom0 and Windows 7
Some HDDs for data
32GB RAM
Linux Mint 13 Mate 64bit on dom0
Windows 7 Professional 64bit on domU with 24GB RAM and 10 threads out of 12 from the CPU (6-core/12 thread)
LVM2 partitioned hard drives for /, /home, and win7 (domU)
Note: I had to blacklist the nouveau driver for the Nvidia card (which is passed through to the Windows domU) else the dom0 would boot.
I also used the passthrough option for xen-pciback instead of the default vpci option in Linux Mint 13 (and probably Ubuntu 12.04) kernels. This passes through the PCI IDs to the domU (Windows in my case).
To get really good disk performance under Windows 7, you must try the GPLPV drivers here: http://wiki.univention.de/index.php?title=Installing-signed-GPLPV-drivers.
Here my Windows experience index:
Unfortunately someone closed the thread I wanted to reply to (full 3d gaming on virtual machine or so). I don't know why that thread was closed - it's really a good one on this subject.
