probably there is some kind of problem with you network-bridge script.
the bondX interfaces, when used as physical interfaces for xen,
should become renamed to pbond0. I miss these in you ifconfig output.
The newly created virtual interfaces will then get the config
from the physical.
Try to use original scripts from xen or that from debian,
maybe is suse doing somthing diffrent, dont know.

cheers
Jaroslaw
