Reboot can't be passed by ACPI.  This is why virDomainReboot is still 
not functional in KVM.  Every other hypervisor does something identical 
to this series.

And a hypervisor initiated shutdown ought to be treated differently than 
an ACPI shutdown.  Namely, it should correspond to an immediate shut 
down vs. prompting the user.

Not all OSes response to ACPI shutdown either FWIW.
