[Xen-users] Re: [Xen-devel] Re: Nvidia 9500GT Xen VGA passthru
Have any of you guys run any 3d benchmarks on your systems?
I have a ~7605 in 3dmark 2k6 with my ATI 5770 (eng sample), 3GB RAM, and
2 cores of my AMD x6 2.8 1055T assigned to the XP vm.

rather old, but xen4 .
contains all i applied to get it working (03_dsdt contains the vBAR/pBAR 1:1
Corei7 CPU on Intel DX58SO
03:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 260]
GFX for Dom0 is:
02:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT]
Dom0 Kernel: 220.127.116.11 from http://code.google.com/p/gentoo-xen-kernel/
its working flawless with winxp (but i can only boot the domU once, shuting it
down and recreating it, makes domu AND dom0 hang... i can live with that
limitation for now)
whats not working is windows7 or vista; can't figure out why

I really have not played with too much after the proof of concept. I do

I've since put the hardware to better use, although I am still intrigued
by Xen. At the time, I was working with a team that was giving serious
consideration to virtualizing their platform, and what better way to
learn than dig in and get my hands dirty.
I tried to include as much detail at the time, with the plethora of
different Xen builds, BIOS's updates, etc.
If someone has something specific I can try to help, but doubtful I will
be of any use. For example, I did not realize Xen 4.x was even
released. Recent projects I've been working on do not lend themselves
well to virtualization; however, I might have to give Xen 4.0 shot -
just to play, of course. There were some serious changes happening with
Xen, the Linux kernel, and KVM when I stopped playing.
I mainly meant if you remember what custom patches did you have to
use/create? Most probably you had to do some vBar=pBar hacking, right?
I guess I'll have to try this myself one day and document the process
with current Xen versions..
Sorry I could not be of more help.

Some people have been asking for tips about Nvidia Xen VGA passthru,
so maybe you could help?
Could you post the exact steps you did?
Have you tried with Xen 4.0.x after your initial experiments in 2009?

I am happy to announce that I have successfully (and finally!) been

-nVidia 9500GT (for VT-d passthrough - DomU)
-nVidia GeForce2 MX200 (Dom0 console)
-Xen (build: xen-unstable, recent as of ~ 1/25/09 1:00AM-EST)
-Dom0: Linux-18.104.22.168-xen (via xen-unstable.hg)
-DomU: Windows XP (pro, sp3, 32-bit)
Once the VT-d bugs were recently corrected (thank you, xen-devel!),
everything went fairly smoothly. Still very buggy yet (its
xen-unstable!), but overall it works.
Make sure support for the PCI-backend is compiled into the kernel
(not just a module) and that you have your pciback.hide options in
grub (late-binding may work, but I haven't tried).
