Yes, you are right.
Listen, as the documentation is not very exaustive, can you explain briefly to me how a guest agent works?
After installing it via the apt-get on the hypervisor (I am using ubuntu as host system) how can I create a script which would do this?
That is waiting for an acpi signal and actually shut down the guest.
And what other operation can you actually do with a guest agent? I would be interested in getting the current amount of memory the guest is using too...as libvirt apis just tell me the max memory allocated.

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.
