Got it working !!!
I finally got it working! Thanks to this thread: http://gro.solexiv.de/2012/08/pci-passthrough-howto posted by another member here.
Some remarks thou:
1. I used PCI passthrough, not VGA passthrough. The latter gave me only troubles. I couldn't load the xen-pciback module before the nouveaux driver took control of the graphics card. Short of compiling the xen-pciback statically into the kernel, I chose to buy a second graphics card. So now I have one graphics card dedicated to dom0, and another to domU.
2. I also got myself a KVM switch to connect keyboard and mouse to two different USB2 ports on two different host controllers. My screen has two DVI ports and I can select between the two via button.
I'm still missing a vital component for my setup - a second DVI-DVI cable which I'll get after the weekend.
So far I managed to install Win7 Ultimate 64 bit into the domU and it even recognized my 2nd video card. I installed the latest driver for it (via the virt-manager vncviewer under dom0). Windows complains about some problems, but this should hopefully be solved once I'm able to connect my display to the second video card (missing cable, how stupid of me).
Once everything is fully functional (with the display connected), I report back with more details.
For those interested, here some system details:
Asus Sabertooth X79 board
i7 3930K with C2 stepping, 10 threads for domU, 2 threads for dom0
AMD 6450 video card for dom0
Nvidia Quadro 600 card for domU
32GB memory, 24GB for domU
120GB Sandisk Extreme SSD
2x 2TB WD hard drives for data (I need to install 2-3 more drives from my old PC)
Linux Mint 13 Maya 64 bit Mate edition with Xen hypervisor as dom0
Win7 Ultimate 64bit as domU
I use LVM partitions for /root, /home, and win7, as well as for the data drives.
Now I need to check how I can make hard drives accessible from within the domU. I've got a lot of data to use under Windows. I guess I need to modify my /etc/xen/win7.cfg file.
