You are probably going to have to start it with systemd.
I don't think that helps does it, systemd doesn't have the ability to
start a program when an X session is started, nor can it stop a
program when X exits.
It's really easy to start a program with systemd once the desktop is up but
I cannot for the life of me figure out a way to stop one.
GUI programs stop when you exit the desktop. I've got one idea I'm going to
try tomorrow and that is wrapping the script in a Java program that opens a
window. If it kills the VM it should kill the script running in it as well.
As far as I can tell all of the programs that are children of
xfce4-session and thus exit when the session ends are compiled
executables and thus probably call session management functions to
handle session shutdown. Most of them in fact have a parameter
"--sm-client-id <id>" which presumably means that the session manager
probably tells them to shut down.
Thus it would seem that a program has to hook into some sort of
session management library function to be able to exit at end of
session.
