Open Stack

Hi Erlon,

I have tested on xena and it works fine. See if you have qos-fip
extension loaded in neution.

# openstack extension list | grep -i qos-fip

| Floating IP QoS

         | qos-fip                                 | The floating IP
Quality of Service extension
                                                              |
