How to send ACPI events to kvm guests

[Christian Roessner <christian@roessner-net.com>]

Hi,

first of all I am not sure, if this is the right place for my question,
so if not, please speak friendly :-)

I use kvm-72 directly over the command line, because I use vde, which is
not enabled in Ubuntu intrepid & co in package libvirt-bin.

Anything is doing really fine, but I can not find out on how to send
ACPI-events to a guest, i.e. power-button.

The libvirt tool seems to be able to do the trick. So what command does
virsh, whatever invoke to send the event?

A friend and I have spend hours and hours with Google, tried to study
the source-code of kvm and libvirt, but could not find the answer.

I want to write s simple init-script for the kvm instances, so I really
would like a clean solution. A bad hack would be ssh guest "shutdown -h
now", but I would prefer the ACPI version, if possible.

So, I hope, somebody may help me with this question.

Thanks alot. I really like kvm.

Kind regards
Christian
