[ovirt-users] Re: OVN Geneve tunnels not been established

Hi Dominik The DC01-node02 was formatted and reinstalled and then attached to ovirt environment. Unfortunately we exhibit the same issue. The new DC01-node02 tries to establish geneve tunnels to his own IP. [root@dc01-node02 ~]# ovs-vsctl show eff2663e-cb10-41b0-93ba-605bb5c7bd78 Bridge br-int fail_mode: secure Port "ovn-95ccb0-0" Interface "ovn-95ccb0-0" type: geneve options: {csum="true", key=flow, remote_ip="dc01-node01_IP"} Port "ovn-be3abc-0" Interface "ovn-be3abc-0" type: geneve options: {csum="true", key=flow, remote_ip="dc01-node02_IP"} Port "ovn-c4b238-0" Interface "ovn-c4b238-0" type: geneve options: {csum="true", key=flow, remote_ip="dc02-node01_IP"} Port br-int Interface br-int type: internal ovs_version: "2.11.0" Is there a way to fix this on the Ovirt engine since this is where the information resides? Something is broken there.
