Designing High-Availability for Xen Virtual Machines with HP Serviceguard for Linux

Appendix Section II

Xen Legacy Control Script (xenhost.sh)

The script was designed for the purpose of Xen VM Legacy Packages. The script functions may be

called from a Legacy Package Control Script through “customer_defined_run_cmds” and

“customer_defined_halt_cmds”. The script depends on the “xenhost.cnf” file for Xen environment

setup.
