Public bug reported:

After the OVN migration, the information about QoS in the neutron DB is correct:
(overcloud) [stack@undercloud-0 ~]$ openstack network show 569b37f1-3dd4-402e-9244-d7fad1ec4804 -c qos_policy_id -f value

(overcloud) [stack@undercloud-0 ~]$ openstack network qos policy show 85d22adf-fc02-4c6d-b17a-36183d206558 -c rules -f value

Wowever there is no QoS information in the OVN NBDB:
