Is there any reason not simply to rely on the dom0's ACPI/pm code for
this?  The dom0 is already driving the bulk of the hardware in the box
either directly or with a bit of minimal indirection through the
hypervisor.  

Having reboot in the HV is massively useful for cases where the dom0 has
crashed and we want to get the box back up, but in most cases, shutdown
is an event that happens when the dom0 is functioning properly.
