[Xen-users] Problems exporting a PCI device to a domU...

[Patrick Gaubatz <patrick@xxxxxxxxxx>]

Hi!

I am trying to export a PCI device (an AVM Fritzcard PCI ISDN card...)  
to a domU but when starting my domU I am getting this error:
"pciback pci-4-0: 22 Couldn't locate PCI device (0000:00:06.0)!  
perhaps already in-use?"
My system is running both debian etch in dom0 and domU...
Below you can find (hopefully) all important  information...

Sincerely,
Gaubatz Patrick
