[Xen-users] domU does not see the pci nic - pci passthrough

["Marco Strullato" <marco.strullato@xxxxxxxxx>]

Hi all!
I want to assign a physical network card  (e100) to a domU: 
I think  Dom0 is ok but domU does not recognize the pci nic.

into DomU I don't know wath should I see: I have nothing in dmesg nor in messages...

Into Dom0 I have

this modules.conf:
options pciback hide=(0000:03:
08.0)
install e100 /sbin/modprobe pciback; /sbin/modprobe --ignore-install e100

This is dmesg:
