Hi all We have a small installation based on OVIRT 4.3. 1 Cluster is based on Centos 7 and the other on OVIRT NG Node image. The environment was stable till an upgrade took place a couple of months ago. As such we had to re-install one of the Centos 7 node and start from scratch. Even though the installation completed successfully and VMs are created, the following are not working as expected: 1. ovn geneve tunnels are not established with the other Centos 7 node in the cluster. 2. Centos 7 node is configured by ovirt engine however no geneve tunnel is established when "ovn-sbctl show" is issued on the engine. 3. no flows are shown on the engine on port 6642 for the ovs db. Does anyone have any experience on how to troubleshoot OVN on ovirt? Thank you
