Hi Pasi,
and thank you for your reply.

Currently I use Debian squeeze as Dom0,
I use a kernel from the devel/xen-pciback-0.6.1 branch at 
git.kernel.org/?p=linux/kernel/git/konrad/xen.git. It is a 3.0.0-rc4 
based kernel.

I have been trying for the last day to get some other Dom0 kernel to 
work but I have so far been unable to get the pciback module to work on 
those kernels (such as the master branch or stable/2.6.39.x). I do 
prefer a fairly late kernel to get problem support for the motherboard 
and cpu.

I have been using a few different Intel drivers, the ones included in 
Windows 7 which are from March and newer ones ( from mid August) but 
with the same result.

I have been trying with a few different boot options, but the last try 
was with the most basic configuration possible. (included as grub.conf.gz)

Also included is the somewhat messy vm config file, xen_htpc1.cfg.gz

I have included startup logs for two different runs, one with Windows 
standard vga drivers (taged with svga_) and with Intel drivers (taged 
with intel_). Not sure if that gives any further clues.

I also added info from lspci -vv.

Did you try latest upstream Linux 3.1-rc3+ ? it includes xen-pciback.

Ok. Maybe Intel developers can comment which driver version should work with win7.

Hi

I have now tried with the new 3.1.0-rc3 kernel (and latest 4.2 XEN), 
with the exact same result. It passthrough works fine before loading the 
proper drivers, but hangs at startup with correct drivers.

I forgot to mention that I did try to install Win 7 on this computer 
without XEN and everything worked fine, so the drivers provided by Intel 
do work.

Um, try the #master brach - it has been updated to 3.0.3.

But the problem is likely not with the kernel - but rather with the
QEMU toolstack. I should one of these days try to pass in some form
of video card to see how it fares.

I just got a DQ67SW+i5-2500 and see the same behavior. I am running 3.1.0-rc8,latest xen-unstable, Windows Server 2008 R2, and the latest Intel September drivers. The VM spins at 100% CPU according to xl top once it transitions tofull graphics mode from the boot splash screen. There is also no response fromthe keyboard after this (i.e. caps lock light won't toggle).
I tried using using VNC as primary video and the IGD as a secondary device. Windows sees the IGD PCI device but complains that it can't be started (even withjust the basic VGA driver). 
I have also been trying to get a cheap ATI card to work (Radeon 3850) as eithera primary and secondary card with no luck at all (not even text output during VMboot). I've tried one of the patches that modifies qemu-dm (pt-graphics.c) that adds some ATI specific bits, but other than some extra debug output in the logfiles, I don't see any difference in behavior.
I am willing to try out new bits/patches if that would help anyone.
Thanks,-mike
