I was thinking about a script that doesn't use virsh.

I would be intrested in what commands virsh uses in it's 'shutdown'
command...

I haven't been working on my own script yet. Up to know i have in mind
to use qemu monitor command 'system_powerdown' and maybe ssh into linux
boxes to get em down (but the latter is not really nice).
By the way when testing manually, i experianced you might want to use
the 'system_powerdown' command twice / execute it two times shortly
after another to get windows machines down.

Greets,
