i was looking hard to get this thing working, and i = somehow manage to get two ATI graphic card working under Windows 7 and Debi= an 6 DomU,
what i learn from all this trying, that the most impor= tant thing is the motherboard!
i had i7 860 with VT-D, but it was hard to find working VT-D motherboa= rd, i try gigabyte P55-USB3 with beta bios from gigabyte and i got working = 3D drivers for a few minutes and then the DomU would crash,
then = i wanted to try asus, but they said that P55 chipset doesnt support VT-D fu= nctions, then i look what David uses and get a MSI motherboard and its defa= ult bios has got VT-D to enable/disable
currenty i have:
i7 860
MSI P55 GD85
ATI= H6670 - working 3D
ATI H5830 - working 3D
Debian 6.0, = custom kernel 3.1
Xen 4.2 unstable ( from repo 2. march? )
Windows 7 64bit - virtual
no extra patches

but how i get it to work is strange, if i enable #gfx_passthru=3D1 = then virtual machine wont start, but if its disabled it starts with virtual= graphic and ATI, but with the primary the virtual graphic
and when i install lates ATI drivers and reboot the machine, it use th= e ATI as the primary graphic and the virtual graphic has ! on it.
i testes with 3D test, even play a game on it, and it works! but as soon i= uninstall the drivers it goes back to virtual graphic as primary graphic c= ard.

Best Regards,
Kristijan Lecnik

Good to know the manual method works.

Isn't it better than nothing? More GPU support could be added lat= er?
