# Script for configuring a vif in routed mode.
|
|
# The hotplugging system will call this script if it is specified either in
|
|
# the device configuration given to Xend, or the default Xend configuration
|
|
# in /etc/xen/xend-config.sxp. If the script is specified in neither of those
|
|
# places, then vif-bridge is the default.
|
|
#
|
|
# Usage:
|
|
# vif-route (add|remove|online|offline)
|
|
#
|
|
# Environment vars:
|
|
# vif vif interface name (required).
|
|
# XENBUS_PATH path to this device's details in the XenStore (required).
|
|
#
|
|
# Read from the store:
|
|
# ip list of IP networks for the vif, space-separated (default given in
|
|
# this script).
