Usually most just add netdev=ethxx to the line in xend-config.sxp that
calls network-bridge.
>From the file (/etc/xen/scripts/network-bridge) :
# Usage:
#
# network-bridge (start|stop|status) {VAR=VAL}*
#
# Vars:
#
# vifnum Virtual device number to use (default 0). Numbers >=8
# require the netback driver to have nloopbacks set to a
# higher value than its default of 8.
# bridge The bridge to use (default xenbr${vifnum}).
# netdev The interface to add to the bridge (default eth${vifnum}).
# antispoof Whether to use iptables to prevent spoofing (default no).
I usually don't use the scripts in /etc/xen/scripts, I let init handle
the bridging on boot, this is because I make a few dummy bridges to use
as 'virtual switches' for my dom-U's to enjoy a private lan and
secondary nic.
My xend-config.sxp calls 'network-dummy' , which is just a script that
exits 0 and does nothing.
