Thread-topic:	[Xen-devel] mkinitrd fails to include 'pciback' module on openSUSE 11.1

The solution, for those who need it, is this:

In /boot/grub/menu.lst:
title Xen -- openSUSE 11.1 - 2.6.27.7-9
    root (hd0,4)
    kernel /boot/xen.gz loglvl=all guest_loglvl=all vtd=1 iommu=1
    module /boot/vmlinuz-2.6.27.7-9-xen
root=/dev/disk/by-id/ata-ST31000528AS_9VP009RT-part5
resume=/dev/disk/by-id/ata-ST31000528AS_9VP009RT-part3 splash=silent
showopts vga=0x31d apic=debug maxcpus=8,
pciback.hide=(0000:03:00.0)(0000:03:00.1)
    module /boot/initrd-2.6.27.7-9-xen

In /etc/init.d/boot.local: 
modprobe pciback hide='(03:00.0)(03:01.0)'
echo -n 0000:03:00.0 > sys/bus/pci/drivers/pciback/permissive
echo -n 0000:03:01.0 > sys/bus/pci/drivers/pciback/permissive

It is important to note that you now need the '0000:' prefix to all of
the pci device addresses used for grub in openSUSE.  

Then the usual entry in your domain config file:

pci = [ '03:00.0', '03:00.1' ]

Cheers,
Phil
