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

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:

This indicates that the tunnels between the hosts are not created.
Can you please check the /var/log/openvswitch/ovn-controller.log on both hosts for errors
and warnings, or share parts of the files here?
If this does not point us to a problem, ovn has to be reconfigured. If possible, most
easy way to do this would be to ensure that
ovirt-provider-ovn is the default network provider of the cluster of the hosts, put one
host after another in maintance mode and reinstall.
