<br>
I'm trying to write a systemd-script (for CentOS7) in order to automatically put the host in "maintenance" on shutdown and to activate it after boot.<br>
I wrote a python-script that to that and it works so that I can start it and see the host in "maintenance" and having all VMs migrated.<br>

Unfortunately I can't call this script on shutdown/reboot and wait until all VMs are migrated and the host is in maintenance.<br></blockquote><div><br></div><div>I don't think this will work, since you must put the host into maintenance, and wait until all vms were migrated before you reboot the host.</div><div><br></div><div>All this can be done only by controlling engine, not from the host that is going to shutdown.</div><div><br></div><div>If you want to trigger this from the host itself, I would write an ovirt-shutdown tool, ask engine to put the host into maintenance, wait until all vms migrate, and the invoke the real shutdown command.</div><div><br></div><div>I guess it would be more useful to run this tool not on the host you want to reboot but on another machine.</div><div><br></div><div>It may be possible to somehow get systemd to use this tool instead of the shutdown command, but I don't think it is a good idea.
