[libvirt] Xen: How to describe bridged network adapter in libvirt-XML?

[Andreas Sommer]

Fortunately I found the problem myself. Maybe I should use schema 
checking from now on, because I put the <interface> element outside 
<devices> by mistake...

A small tip: "virsh dumpxml" is very good for finding out the 
configuration of Xen domains.

 Andreas
