Okay, now I have the local network back, but what now? This is the current

If I start /etc/xen/scripts/network-bridge start I get back the "tmpbridge" 
and the messages:
irrlicht@home:~$ sudo /etc/xen/scripts/network-bridge start
ifdown: interface peth0 not configured
RTNETLINK answers: Device or resource busy

That doesn't kill my network anymore, but what to do next?

THanks,
Daniel
