Public bug reported:

This is mainly following https://docs.openstack.org/neutron/pike/admin
/config-qos.html, steps to reproduce:

1. Admin creates qos policy "default" in admin project
2. User creates network "mynet" in user project
3. Admin applies qos policy to tenant network via "openstack network set --qos-policy default mynet"
4. User tries to create (an instance with) a port in "mynet".

Result: Neutron fails with "Internal server error". q-svc.log shows
