[Xen-users] PCI Passthrough

[Alex.Pearson@xxxxxxxxxxxxxxxxx]

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
pciback.hide=(0000:00:1d.0)(0000:00:1d.2)(0000:00:02.0)(0000:00:1f.3)

Dmsg output:

itops10:/boot/grub# dmesg | grep Unk
Unknown boot option
`pciback.hide=(0000:00:1d.0)(0000:00:1d.2)(0000:00:02.0)(0000:00:1f.3)':
ignoring

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

Alex
