xend doesn't send the ACPI Shutdown (which would simulate a "power button 
push" event in the ACPI-aware OS) command to the QEmu monitor for the 
HVM?  Not sure what the exact qemu command is (can never seem to get 
the 'help' command in the qemu monitor to show just one page of help 
topics).

Using KVM (which uses the same or similar qemu support) you can issue a 
shutdown command in the qemu monitor, or via the host, and it will show 
as an acpi shutdown request in the guest OS, and it will (if ACPI support 
works in the guest) do a graceful shutdown.
