Susanne,

1. Create bridges and assign correct parameters to them
  brctl addbr xen-br1
  brctl stp xen-br1 off
  brctl setfd xen-br1 0
  sleep 3
  ifconfig xen-br1 up

2. Change your config files for domains according
  /etc/xen/dom1
    vif = ['mac=aa:00:00:00:01:00, bridge=xen-br1']

  /etc/xen/dom2
    vif = ['mac=aa:00:00:00:02:00, bridge=xen-br1']

3. Configure the dom1 and dom2 /etc/sysconfig/network
interfaces files (ifcfg-eth0) with the correct IP address,
netmask, network and broadcast numbers.

4. Boot both domains, and you are done.

Be aware: xen start scripts do not take care of more
than one bridge. You change then according to your
needs, or create your own scripts.

All above is true for SUSE Linux 9.2 Professional with
Xen compiled from source.
