I am trying to setup a driver domain for a NIC.

I have passed through the device successfully and set
netif=1 in the driver domain config.
I also added the config to a guest domain vif=['backend=7']
(7 is the ID of the driver domain)

xenstore-ls /local/domain/7/backend/vif

shows that the state of the device is 1 (initializing)
(see below the email for the output)

On the guest I get:
XENBUS: Waiting for devices to initialise: 295s...290s...

And then we it finally boots I get:
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00

I am running xen-unstable.
The driver domain is Ubuntu HVM guest.
It is a VT-d system.
The device being passed is:
Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02)

Suggestions on how to debug?

Thanks in advance for any suggestions,
