Hi,
as I expected. Brooktree and Philips attached to the same bridge. If you are not
able to patch Xen before building it, I think you have to find a combination
that
comes out of the box.
BR,
Carsten.

Unfortunally I'm not familar with patching.
On my system pci looks

It was working with Kernel 2.6.18 under debian etch. Now I installed
lenny, had ubuntu 8.04 and 8.10 before. xmI will use a small script to
pass the parameters...
#/bash/sh
xm create lenny50.cfg -c pci='11:00.0' pci='11:09.0'
This brings in the domU the following list:
lenny50:~# lspci -tv
-[0000:00]-+-00.0 Philips Semiconductors SAA7146
\-01.0 Philips Semiconductors SAA7146
It should work.
Maybe one day there will be version with all the benefits and a unified
interface...
Thanks
