[Xen-users] pciback.hide with ISDN Cards

[Gerhard Possler <gerhard.possler@xxxxxxxxxx>]

Hi all,

did somebody successfuly export ISDN
Cards to DomU?

I want to have 2 ISDN Cards in DomU
(for Asterisk with mISDN)

There are 2 ISDN Card under following
PCI Adresses: 0000:01:00.0 and 0000:01:01.0
 
so under /boot/grub/menu.lst:
title XEN -- openSUSE 10.3 - PAE
    root (hd0,4)
    kernel /xen-pae.gz pciback.hide=(0000:01:00.0)(0000:01:01.0)
    module /vmlinuz-2.6.22.13-0.3-xenpae
root=/dev/mapper/nvidia_deihceca_part7 vga=normal resume=/dev/mapper/nvidia_deihceca_part6
splash=silent showopts
    module /initrd-2.6.22.13-0.3-xenpae

and under /etc/modprobe.conf.local:
options pciback hide=(0000:01:00.0)(0000:01:01.0)
install hfcpci /sbin/modprobe pciback
; /sbin/modprobe --first-time --ignore-install hfcpci

even combinations of above config and
also when using the address short form 01:00.0 and 01:01.0 does't export
the device, in all cases the start of DomU shows:
Using config file "/etc/xen/vm/opensuse".
Error: pci: failed to locate device
and parse it's resources - [Errno 2] No such file or directory: '/sys/bus/pci/devices/0000:01:00.0/driver'

DomU config file is:
name="opensuse"
ostype="opensuse"
uuid="b24449ce-e89a-b107-a96a-da91ce26651f"
memory=384
vcpus=1

>
>
>
localtime=0
builder="linux"
bootloader="/usr/lib/xen/boot/domUloader.py"
bootargs="--entry=xvda2:/boot/vmlinuz-xenpae,/boot/initrd-xenpae"
disk=[ 'file:/srv/xen/opencave/hda,xvda,w', ]
vif=[ 'mac=00:16:3e:00:00:01', ]
nographic=1
pci=[ '01,00,0', '01,01,0' ]

I don't belive it is the openSUSE kernel 2.6.22.13-0.3-xenpae because on an identical system with an 3Com NIC the export of the PCI device works perfect...
Here it's enough to set in /etc/modprobe.conf.local:
options pciback hide (02:0d.0)
install 3c59x /sbin/modprobe pciback ; /sbin/modprobe --first-time --ignore-install 3c59x

also commenting out the eth1 device in /etc/modprobe.conf and remove network config for eth1.


I'm a little bit confused  because the working mISDN doesn't show an any hfcpci device under /sys/bus/pci/drivers that i could unbind...


So the question is did somebody export ISDN PCI devices to DomU (Vendor doesn't matter)
