Open Stack

Hi,

I'm about ready to go into production with kolla, but one small issue 
remains. On regular Openstack deployments, I would use the 
libvirt-guests service to ensure that VMs on hosts always shutdown 
cleanly when the host shuts down. This is to prevent database issues 
which may happen on guests during forced, unclean shutdowns.

At first glance, Kolla doesn't seem to install this service or anything 
similar that would ensure clean shutdown of guests when the host shuts 
down. I have found in the github source, in the tools folder, a systemd 
script that is supposed to do that, but it tries to execute 
/usr/libexec/libvirt-guests.sh shutdown in the libvirt container, which 
doesn't exist there.

Does Kolla already ensure clean shutdown automatically, or is there a 
script I'm missing that could make this work?
