Nicolas,
I am following this thread with interest as a system I was about to setup is using the same driver and in the same networking scenario! If in a small segment with only one subnet and the default gateway on that subnet as you describe above, the Xen machine even in bridged mode won't have connectivity if Dom0 has an ip on the same subnet? Giving the Xen machine an IP on a different subnet would make it tricky to connect from another machine in this setup?

Thanks!
