Hi Miguel,
I had read some blogs about OVN and I tried to collect some data that might hint where the
issue is.
I still struggle to "decode" that , but it may be easier for you or anyone on
the list.
I am eager to receive your reply.
Thanks in advance and Happy New Year !
Best Regards,Strahil Nikolov

That's a good question.ovirtmgmt is using linux bridge, but I'm not so sure
about the br-int.'brctl show' is not understanding what type is br-int , so I
guess openvswitch.
This is still a guess, so you can give me the command to verify that :)
As the system was first build on 4.2.7 , most probably it never used anything except
openvswitch.
Thanks in advance for your help. I really appreciate that.

Hi Dominik,
sadly reinstall of all hosts is not helping.
@ Miguel,
I have 2 clusters
1. Default (amd-based one) -> ovirt1 (192.168.1.90) & ovirt2 (192.168.1.64)
2. Intel (intel-based one and a gluster arbiter) -> ovirt3 (192.168.1.41)
But what are the switch types used on the clusters: openvswitch *or*
legacy / linux bridges ?
The output of the 2 commands (after I run reinstall on all hosts ):

If you know an easy method to reach default settings will be best, as I'm currently
not using OVN in production (just for tests and to learn more about how it works) and I
can afford any kind of downtime.
