Hi Bastian,

Thanks for that info. I have now been able to get the nic seen in the
domU, however the link of the nic is reported as down.

I get the following error on the screen " pci frontend enable msi
failed for dev 0:0"

I have connected this link on a cross-over connection to another
system, the link on the other system  shows it as up. So I am sure the
link is up, but the DomU incorrectly shows it as down.

Any idea on whats going wrong?
