If your guest OS supports it, you could probably write two scripts that uses virtio_console(4), one for the guest to tell the host "HELLO" and one for the host to say "NICE TO SEE YOU!" once the guest's "HELLO" is received. Of course, replace the "HELLO" and "NICE TO SEE YOU!" with the right logic you're looking for. ;) The "HELLO" bit could be written as an init script.
