I'd recommend extending the scope of this to cover the full scope of the (not well documented) libvirt-guests service
including /etc/sysconfig/libvirt-guests  configurations, etc.

Will do a full evaluation of the libvirt-guests service

libvirt-guests won't be run to shutdown guests if the host is "stuck" or "powered off" as suggested in the introduction to this note - it will only shutdown the guests if the host is shutdown properly.

Also you had asked (in email I think) if the file that needs to be edited is on the host or the guest - it is on the host.

Beyond that, probably someone with a better knowledge of the libvirt-guests service should look over your addition. Cole - weren't you the original author?

Original author was Jiri

Step 2 should rather be:

2. Start the libvirt-guests service
If you have not started the service, start the libvirt-guests service.

That is, if the service has already been started, it should not be restarted because stopping the service would cause shutdown of all running domains.

Closing as CURRENTRELEASE since this is now available in RHEL 6.5 GA.
