Thread-topic: [Xen-devel] RE: Partial Success VGA passthrough NVIDIA GeForce 7600 GS on Intel 5520
Don't use latest pv-ops dom0, pls try below xen, qemu and dom0 version which 
was tested and worked for Geforce 8400 GS passthrough with my sent patches:
        Xen changeset: 20143
        Qemu commit: 0fdbb469
        2.6.18 dom0 changeset: 844

We didn't test with GeForce 7600 GS, if you still failed on above environment. 
It's possibly the card is specific and needs extra hacks to make it work.

I'm not sure which issues I was having when I tried to use changeset 
20143 a month ago, since I was able to check out changeset 20143, and 
apply the patches successfully when I tried again today.  Weird.  I 
applied the same patches that Mr. Teo En Ming listed in his email 
http://article.gmane.org/gmane.comp.emulators.xen.devel/71101.  They all 
applied cleanly.  So, I'm now running what should be the same setup as 
Mr. Teo En Ming from what I can tell, except that my vBar-pBAR patch is 
for my machine, and I'm using the latest pv-ops.

I succeeded in creating an XP HVM guest, but I can't get the drivers to 
work.  When I boot XP, the console output for dom0 switches to the 
second graphics card, and any console output messes with the display 
output.  I don't know if this is an issue, or merely a nuisance.  Once I 
install the NVIDIA drivers and reboot, it reverts back to 640x480, 16 
colors, and the device manager reports that the device could not start 
(Code 10).  So, that's not working.  Any suggestions on what to try or 
look for?

lspci -vvv on a Linux domU still reports the same problem with the 
expansion ROM as before.
