I have no domU started (only Dom0 is running).

The first interface eth0 with mac address 00:14:5E:0A:53:04 is correct
and works fine. After starting xend it has gone, replaced bei peth0 with
the mac address FE:FF:FF:FF:FF:FF.

peth0 should be a physical interface, isn't it? Or do you don't have any
physical interfaces? how shows your ifconfig completly?

Well, and does this work? Because in my configuration it does not.
