#============================================================================

# Default Xen network start/stop script.
|
||
|
|
# Xend calls a network script when it starts.
|
||
|
|
# The script name to use is defined in ${XEN_CONFIG_DIR}/xend-config.sxp
|
||
|
|
# in the network-script field.
|
||
|
|
#
|
||
|
|
# This script creates a virtual switch (default ${netdev}) and adds a
|
||
|
|
# device (defaults to eth0) to it. The interface that this Open vSwitch
|
||
|
|
# is created on should not have a working IP address and will be used as
|
||
|
|
# a switch for Xen domU's.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# network-openvswitch (start|stop|status) {VAR=VAL}*
|
||
|
|
#
|
||
|
|
# Vars:
|
||
|
|
# bridge The bridge to use (default xenvs0).
|
||
|
|
# netdev The interface to add to the bridge (default eth0). This
|
||
|
|
# device should not be configured with an IP address. If so
|
||
|
|
# this script will tear down the interface and bring it back up
|
||
|
|
# without an IP address.
|
||
|
|
#
|
||
|
|
# start:
|
||
|
|
# Creates the bridge as bridge
|
||
|
|
# Enslaves netdev to bridge
|
||
|
|
#
|
