Hi,
because on Fedora/RHEL we use systemd dependencies and so we have 3
(main) service files: openvswitch.spec, ovs-vswitchd.spec and
ovsdb-server.spec that are interconnected (see rhel/README.RHEL.rst).

If you use ovs-ctl directly systemd will loose tracks of the new
ovsdb-server and ovs-vswitchd processes and so you can't restart it by
using "systemctl restart".

Moreover it seems ovs-vswitchd is not restarted correctly in this case.
