[Xen-users] XEN 3.3 - pci in domU does not work

[christian <grassu@xxxxxxxxxxxxxx>]

Hi,

I installed xen 3.3 on a gentoo x86_64 system. I'm trying to
passthrough a pci isdn card to one domU. When I start the domU I
receive this error:

> xm create -c /etc/xen/gentoo-samba pci=0a:02.0
> Using config file "/etc/xen/gentoo-samba".
> Error: unsupported format character ':' (0x3a) at index 6

So I tried to replace the ':' character with an '.' . Then the domU
starts but there is no pci device.

Any ideas?
Thanks in advance for any help.


Here is my system config and xen setup:

grub:
> module /kernel_2.6.21-xen0 root=/dev/sda3 pciback.permissive 
> pciback.hide=(0a:02.0) max_loop=16

 uname -a:
