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.

@Miguel Duarte de Mora Barroso <[email protected]> Is there a hardcore
way bypassing ovirt-provider-ovn to do this?

Yes, a fedora VM in oVirt works great and creating a template from the
images from ovirt-image-repository is comfortable.
