Thanks for your advice!
I adjusted the interfaces file so that the xenbr0 ius created there,
the system can be sucessfully booted with the attached configuration
communicating over VLAN 94 with the network.

I do not yet understand which component is going to create the vifX.Y 
interfaces
needed to start successfully the DomU's ?

xm create yields:
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

The system ist running the latest debian/unstable tree,
so there is udev but no hotplug package.
