[solved] openvswitch + missing port

[darthbolek]

Fresh Centos 7 (in KVM, netinstall, today) and openvswitch 2.10.1
Problem: after adding extra port and restarting network service the port is gone. I need this port to be permanent. Obviously I am missing something...
Log (/var/log/openvswitch/ovs-vswitchd.log) confirms that all 3 ports were removed, but only 2 were recreated

[aaa@bbb ~]$ sudo ovs-vsctl add-port ovs-main mgmt0 -- set interface mgmt0 type=internal
[aaa@bbb ~]$ sudo ovs-vsctl show

And what happens when you restart NetworkManager.service ?

[darthbolek]

NetworkManager is disabled and not used.
