Re: [Xen-users] pciback.hide with ISDN Cards

[Stephan Seitz <s.seitz@xxxxxxxxxxxx>]

Hi,

we've done this with a fritz pci isdn card successfully.
as that machine in no way uses the isdn stack at dom0,
i removed the kernel module and rebuild the dom0's initrd
without this module (I didn't trust the /etc/modprobe ;) )

one line from the lspci:

03:01.0 Network controller: AVM Audiovisuelles MKTG & Computer System GmbH 
Fritz!PCI v2.0 ISDN (rev 02)

the grub entry:

title           Xen 3.1-i386-pae / Ubuntu, kernel 2.6.20-100-server
root            (hd0,1)
kernel          /xen-3.1-i386-pae.gz
module          /vmlinuz-2.6.20-100-server 
root=UUID=09503299-c560-45de-b69d-8d98eadc7b23 ro console=tty0 irq=poll
pciback.hide=(03:01.0)
module          /initrd.img-2.6.20-100-server
quiet
savedefault

the domU conf:

kernel = '/boot/vmlinuz-2.6.19-4-server'
ramdisk = '/boot/initrd.img-2.6.19-4-server'
memory  = '1832'
cpus="0"
root    = '/dev/sda1 ro'
disk    = [ 'phy:vg0/XXXXX-disk,sda1,w', 'phy:vg0/XXXXX-swap,sda2,w' ]
name    = 'XXXXX'
vif  = [ 'mac=XX:XX:XX:XX:XX, bridge=xenbr0', ' mac=XX:XX:XX:XX:XX:XX, 
bridge=xenbr1' ]
pci = [ '03:01.0' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

Hope this helps.

Regards,

Stephan
