[Xen-users] PCI Passthrough

Hi All,

      I'm hoping someone can help, because this is driving me mad!  I've
been through the docs and the mailing list archives again and again, but
with no luck!
I just can't get PCI passthrough to work.  Here are the errors i get:

Grub config:

title Xen 3.0 / XenLinux 2.6.12
        root (hd0,0)
        kernel /xen.gz dom0_mem=131072 com1=115200,8n1
        module /vmlinuz-2.6.12-xen0 root=/dev/hda2 ro console=ttyS0, 115200

Dmsg output:

itops10:/boot/grub# dmesg | grep Unk
Unknown boot option

Non of the devices are hidden when i do a lspci
I'm assuming this is because i'm doing something wrong, if i try to start a
machine regardless then i get the following, however i assume this is
because the hosts not configured:

itops10:/boot/grub# grep pci /etc/xen/itops9
pci = ['00:02.0','00:1f.3','00:1d.2','00:1d.0']

itops10:/boot/grub# xm create itops9
Using config file "/etc/xen/itops9".
Error: Invalid pci specifier: 00:02.0

Any help would be much appreciated, i know someone on the list has got this
working, but could find any articles relating to any problems like this :-(
Am i missing some kernel modules?  Which ones, i've had a good look through
and can't find any obvious candidates

Thanks in Advance
