|
# Script for configuring a vif in openvswitch mode.
|
|
#
|
|
# Usage:
|
|
# vif-openvswitch (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:
|
|
# bridge openvswitch to add the vif to (required).
|
|
# ip list of IP networks for the vif, space-separated (optional).
|
|
#
|
|
# up:
|
|
# Enslaves the vif interface to the bridge and adds iptables rules
|
|
# for its ip addresses (if any).
|
|
#
|
|
# down:
|
|
# Removes the vif interface from the bridge and removes the iptables
|
|
# rules for its ip addresses (if any).
