Title: Xen HVM ACPI shutdown

Hi there,

It's long time that Xen support the graceful shutdown for HVM even without PV drivers. It use ACPI features and the Guest should be configured to manage it (http://old-list-archives.xen.org/archives/html/xen-devel/2009-04/msg00065.html).

This simple patch allow you to choose the ACPI method instead of the standard "shutdown".
The standard shutdown command without PV drivers cause a brutal power off with potential filesystem corruptions.

Ettore Simone
