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. /Erik On 08/28/2011 12:15 PM, Pasi Kärkkäinen wrote: > On Sat, Aug 27, 2011 at 08:51:40PM +0200, Erik Lind wrote: >> 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.
