Hi Dominik,
Thanks for your reply.
On ovirt1 I got the following:
[root@ovirt1 openvswitch]# less ovn-controller.log-20191216.gz
2019-12-15T01:49:02.988Z|00032|vlog|INFO|opened log file
/var/log/openvswitch/ovn-controller.log
2019-12-16T01:18:02.114Z|00033|vlog|INFO|closing log file
ovn-controller.log-20191216.gz (END)
Same is on the other node:
[root@ovirt2 openvswitch]# less ovn-controller.log-20191216.gz
2019-12-15T01:26:03.477Z|00028|vlog|INFO|opened log file
/var/log/openvswitch/ovn-controller.log
2019-12-16T01:30:01.718Z|00029|vlog|INFO|closing log file
ovn-controller.log-20191216.gz (END)
The strange thing is that the geneve tunnels are there:
