Hello Gianluca,
Please check on the engine what hosts are registered on ovn-north: #ovn-sbctl show
For each registered host you should see something like: Chassis "69b6b2a6-5afb-4908-8d66-c648cbe09ba8" hostname: "f43" Encap geneve ip: "192.168.120.43" ....
I would assume you have some unwanted entries there (10.4.168.74)
To get rid of this please use: # ovn-sbctl chassis-del <chassis id> // for example: ovn-sbctl chassis-del 69b6b2a6-5afb-4908-8d66-c648cbe09ba8
Please let me know if this helps.
Note also that you would have to runplug/plug any vnics on any vm's you have on those two hosts.

Hello Marcin. it worked like a charm.. ;-) The "show" option of the command returned 4 chassis: - 3 are of running oVirt hosts that I notice have been automatically updated after the "vdsm-tool ovn-config ..." command run on them (their dns name has remained the same) - the leftover one After removing it with the suggested command it disappeared both from engine (ovn-sbctl show) and from hosts (ovs-vsctl show) I'm going to power on some VMs with their nics on OVN and see if all is ok. Thank you very much. Gianluca
