Hello Teo,
I am not clear what you say. Could you tell me the IP address of domU?

Dear Caz,
I have the Intel Corporation 82567LM-3 Gigabit Network Connection on my
Intel DQ45CB Desktop Board.
There is only one network interface on my computer and it is eth0.
When I start xend, it creates ethernet bridge eth0. My Dom 0 and Win XP
Dom U share the same ethernet bridge.
On Dom 0, IP address is configured on the bridge eth0. In my Win XP dom
U configuration, I specified vif = [ 'bridge=eth0' ]
So my Dom 0 and Dom U are sharing the same bridge, and hence the same
physical network card.
