The ovirt nb log contains:

In my ovn-controller.log of my 3 hosts I have this, when I run the 2
commands below on the provider host

ovn-sbctl set-connection ptcp:6642
ovn-nbctl set-connection ptcp:6641

On my provider I see then the 3 oVirt hosts connected:
[root at ovmgr1 openvswitch]# netstat -tpn|grep 66
tcp        0      0 10.4.192.43:6642        10.4.168.76:38882

tcp        0      0 10.4.192.43:6642        10.4.168.75:45486

[root at ovmgr1 openvswitch]#

But it seems that the "set" command above is not persistent across reboot
of the provider host.... that in my case is the oVirt engine server
