'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).
