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

It's most likely that your PCI devices reside on the same PCI bridge. When
including
support for FLR, a requirement check was added to have all PCI devices that
reside on
one PCI bridge to be co-assiged to one DomU, although that's not necessary when
the
DomU is PV.
You can check with lspci -tv whether this is the case and when you use pv domains,
you might use this patch that will disable FLR and this kind of message.
BR,
Carsten.

Betreff: [Xen-users] Paramters for PCI passthrough in config file
Hi,
I was trying now since two weeks to pass pci cards to different domU's.
First I used XEN 3.3, but there I got error messages like
must be co-assigned to the same guest , so I switched to other distris and
versions.
Now I have:
mainserver:/etc/xen# xm info
host : server
release : 2.6.26-1-xen-amd64

and run into the problem that I can pass only one pci to a DomU. I use the
following parameters in the /etc/xen/domU.cfg
pci = [ '11:00.0','11:09:0' ]
I have tried different versions like
pci = [ '11:00.0', '11:09:0' ] or
pci = [ '0000:11:00.0', '0000:11:09:0' ] and so on.
The only solution is to pass these parameters with the command line, like:
server:/etc/xen# xm create DomU.cfg -c pci='11:00.0' pci='11:09.0'
Then I get two PCI cards inside the DomU.
Does anyone know how to pass them correctly inside the config file.
Thanks
Hans
