Re: [Xen-users] Success VGA passthrough on windows 7 x64 with Xen 4.2.1-pre

I did some researches to find out how I did install drivers for nvidia vga under windows 7 DomU and this is my conclusion. No matter how system is prepared, Dom0 and hardware, if it works with windows xp then could work with windows 7 (my testing platform had Dom0 kernel 3.6-rc7 with xen 4.2.1-pre). Most important thing is how to foul windows to accept drivers. This is how I did this. Three separate installations of windows 7 and each time success:

1) for windows 7 installation in DomU configuration setup like this:
#pci = ['1:00.0']  // in my case NVIDIA VGA BDF is 1:00.0
#pci_msitranslate = 

2) when You install windows 7 shut it down and change DomU config. show vga to windows but don't pass it thru yet:
pci = ['1:00.0']  
#pci_msitranslate = 

3) start DomU and install nvidia drivers. in my case 275.33 or 275.50, both work and I didnt check newer

4) shut down DomU and setup his configuration. its finally configuration in my case :
pci = ['1:00.0'] 
#pci_msitranslate = 

5*)create DomU and drivers could works and no error 43

* because my system setup i need to restart Dom0  before step 5
** if there still will be reported problem with drivers under windows 7 I will make more researches for different kernels/Dom0 configurations
