The systemd script does call another script in the container. Here, lets 
look at this snippet from the systemd script at 
https://github.com/openstack/kolla-ansible/blob/master/tools/kolla-libvirt-guests.service 
:

ExecStart=-/usr/bin/docker exec nova_libvirt /bin/rm -f 
/var/lib/libvirt/libvirt-guests
ExecStart=-/usr/bin/docker start nova_compute
ExecStop=/usr/bin/docker stop nova_compute

ExecStop=/usr/bin/docker exec nova_libvirt /bin/sh -x 
/usr/libexec/libvirt-guests.sh shutdown

It looks like it removes the libvirt-guests regular script if it's 
present when it starts and starts a different script with the shutdown 
argument when it stops. This second script is the one missing from my 
installed container image, hence why I am confused.
