thank you for your answer. I looked at wiki entry and as Steffen also told me, I can see, that in Xen 3.2.x the bridge names have changed from 3.1.x -> 3.2.x
So I tried what I found in almost every howto and book:

server:/etc/xen/scripts# ./network-bridge bridge=eth1 netdev=eth1 start
    ifdown: interface eth1 not configured
    Nothing to flush.
    Waiting for peth1 to negotiate link......
    Ignoring unknown interface eth1=eth1

Are your physical interfaces configured? 3.2 bridge script scrapes off the information from netdev and applies it to bridge. If your netdev is not up and running by the time network-bridge is run I am not sure it will be able to stand up the bridge.

Before you run your network-bridge scripts check the output of ifconfig and make sure each physical interface is mentioned and has an ip.
