-# Default Xen network start/stop script.
-# Xend calls a network script when it starts.
-# The script name to use is defined in /etc/xen/xend-config.sxp
-# in the network-script field.
-#
-# This script creates a bridge (default xen-br0), adds a device
-# (default eth0) to it, copies the IP addresses from the device
-# to the bridge and adjusts the routes accordingly.
-#
-# If all goes well, this should ensure that networking stays up.
-# However, some configurations are upset by this, especially
-# NFS roots. If the bridged setup does not meet your needs,
-# configure a different script, for example using routing instead.
-#
-# Usage:
-#
-# network (start|stop|status) {VAR=VAL}*
-#
-# Vars:
-#
-# bridge The bridge to use (default xen-br0).
-# netdev The interface to add to the bridge (default eth0).
