I'm very confused here; you mention that on engine there are 2
switches for every ovn network, but, on your ovn-nbctl list
logical_switch output I can clearly see the 2 logical switches where
the OVN logical networks are stored. Who created those ?

I think it could be related to the situation described here (it is the same environment, in the meantime updated also from 4.2.8 to 4.3.1) and previous configuration not backed up at that time:

and some steps not done correctly by me.
After following indications, I tried to import ovn but probably I did it wrong.
 

Could you show us the properties of those 2 networks ? (e.g. ovn-nbctl
list logical_switch 32367d8a-460f-4447-b35a-abe9ea5187e0 & ovn-nbctl
list logical_switch 64c4c17f-cd67-4e29-939e-2b952495159f)

@Gianluca Cecchi , I notice that one of your duplicate networks -
'ovn192'  - has no ports attached. That makes it the perfect candidate
to be deleted, and see if it becomes 'listable' on engine. That would
help rule out the 'duplicate name' theory.

 I can try. Can you give me the command to be run?
It is a test oVirt so It would be not a big problem in case of failures in this respect.


At the moment, I can't think of a better alternative. Let's see if
Marcin comes up with a better test / idea / alternative.

Also, please let us know the version of the ovirt-provider-ovn,
openvswitch-ovn-central, and openvswitch-ovn-host.

On engine:
[root@ovmgr1 ~]# rpm -q ovirt-provider-ovn openvswitch-ovn-central openvswitch-ovn-host
ovirt-provider-ovn-1.2.20-1.el7.noarch
openvswitch-ovn-central-2.10.1-3.el7.x86_64
package openvswitch-ovn-host is not installed
[root@ovmgr1 ~]# 

On the 3 hosts I only have this package installed:
openvswitch-ovn-host-2.10.1-3.el7.x86_64

 Thanks
Gianluca
