I think I remember that I also needed the ip=10.0.1.1 argument. Not to
initialise the network in the domU (I do this via ifconfig, route) but
the get the IP address of the dom0 (=gateway) in the 10.x.x.x network.

Specifying ip=10.0.1.1 seems to ensures that dom0 gets the address
10.0.1.128 whereas it otherwise could get 10.0.2.128 or whatever and
makes it impossible to use a not dhcp setup with routing.

At least this is what I vague remember ...
