Hi Dominic

That fixed it.
VMs have full connectivity and I don't see any errors on the nodes ovn
controller.

Thanks for the help and quick responses, I really appreciate it.

In summary for future reference:
If certificate errors are met need to review:

ovs-vsctl --no-wait get open . external-ids:ovn-remote
ovs-vsctl --no-wait get open . external-ids:ovn-encap-type
ovs-vsctl --no-wait get open . external-ids:ovn-encap-ip

The ovn-remote will state if the OVN connection is using TCP or TLS.

We then do:

ovn-nbctl get-ssl
ovn-nbctl get-connection
ovn-sbctl get-ssl
ovn-sbctl get-connection
ls -l /etc/pki/ovirt-engine/keys/ovn-*


As to check the ovn northbound and southbound configuration and listening
ports and if TCP or TLS is used.

If tls is used we must update the nodes with:

ovn-nbctl set-ssl "ovn northbound interface certificate key" "ovn
northbound interface certificate file"
ovn-nbctl set-connection pssl:6641
ovn-sbctl set-ssl "ovn southbound interface certificate key" "ovn
southbound interface certificate file"
ovn-sbctl set-connection pssl:6642


The certificates must reside within nodes through the VDSM client.

Finally, we check that all tunnels are established and working ok.

If we get to a stuck chassis we simply stop the ovn service on the node and
delete the chassis from the northbound interface through:

ovn-sbctl  chassis-del "chassis_ID"

Thank you
Best Regards
Konstantinos Betsis
