Comment 17 for bug 368962

Could someone point me to documentation on how to send an ACPI signal to a vm so I can script my own solution as has been suggested?

Andrew: It appears that the xml already has room for this: http://libvir.org/formatdomain.html#elementsFeatures

I have been able to shutdown by installing acpid package on the guest (not the acpi package) and proven that the shutdown capability can work. It took me awhile to figure that out so I'll just mention that here to save someone time.
