Hello

I'm trying to deploy Openstack with OVN(Open Virtual Network)

I'm following this guide page: https://www.server-world.info/en/note?os=Ubuntu_20.04&p=openstack_wallaby2&f=14

My problem is, I can't create new instance due to port binding failure

nova-compute log from compute node sayss:

"nova.exception.PortBindingFailed: Binding failed for port "", please check neutron logs for more information."

This is output of "tail /var/log/ovn/ovn-controller.log" on that compute node

ovsdb-server log has nothing interesting

This is output of "tail /var/log/openvswitch/ovs-vswitchd.log"
