libvirt users - Apr 2015 - virsh shutdown <domain> not fully working on win7 ?

hello list,

i have a running vm with win7.
When i fire up an 'virsh shutdown win7' nothing happens.
When i fire up a second the same command, then the win7 machine is 
shutting down.
Why do i need to fire up this command twice?
Any ideas?

best regards

marko

I have the same issue with a Win8. After the second (and succesfull) shutdown
command, I check the events after reboot and see that it was still a clean
shutdown. So I didn't give it more attention...

'virsh shutdown' requires guest cooperation. In particular, if you have
not hooked up a guest agent, then all it can do is send an ACPI signal
into the guest, but it is up to the guest whether it shuts down on
receipt of that signal (and not all guests do).

Being a bit late... From my experience, the windows guest does
recognize ACPI signal when one of two conditions are met: the signal
was sent *twice* in a short period, or you had issued C-A-D on the
standard input before. I do not understand why the Microsoft did
things exactly this way, but that`s how it works (or may work).
