Guest shutdown is ALWAYS a cooperative action.  It sounds like your
guest defaults to an interactive shutdown when an ACPI shutdown request
is received.  You can install qemu-guest-agent in your guest and send
shutdown via the agent instead of via ACPI - that may be a bit more
responsive at doing an immediate shutdown.  But beyond that, no, there
is no way to guarantee a graceful guest shutdown without guest
cooperation.  If you must stop a guest, and shutdown is taking too long
because the guest is not cooperating, then use the 'virsh destroy' command.
