I could enter the guest and change this default behaviour and it actually
works..but I'd like for a way to send a shutdown command without doing so.
Is it possible?
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.
