# xend-relocation
#
# Version = 1.0.3
# Date = 2007-09-14
#
# Maintainer(s) = Ron Terry - ron (at) pronetworkconsulting (dot) com
#
# The latest version can be found at:
#
# http://pronetworkconsulting.com/linux/scripts/xend-relocation.html
#
# Description:
#
# This script is used to enable or disable the VM relocation (migration)
# feature of xend. It can be used to manage the local instance of xend
# or both the local instance and instances of xend on the other machines
# to/from which VMs can be relocated.
# To manage the instances of xend on other machines this script communicates
# using ssh so it is recomended that if you use this feature you
# pre-distribute ssh keys between the servers.
#
# Depends on:
#
# Can use: /etc/sysconfig/xend
#
# Usage: xend-relocation (start|stop|status)
# or
# xend-relocation (on|off|status)
#
# Vars:
#
# XEN_CONFIG_FILE
#
# RELOCATION_NODELIST
#
# MANAGE_ALL_RELOCATION_NODES
#
# XEN_RELOCATION_PORT
#
#============================================================================
#### Read config files and set variables ##################################
# If you source the /etc/sysconfig/xend file comment out the variables
# being set in this script.
