4 Nova leaks bandwidth resources if a bound port that has QoS minimum
5 bandwidth rules is deleted in Neutron before the port is logically detached
6 from the server. To avoid any leaks, users should detach the port from the
7 server using the Nova API first before deleting the port in Neutron. If the
8 server is in a state such that the port cannot be detached using the Nova
9 API, bandwidth resources will be freed when the server is deleted. Another
10 alternative to clean up the leak is to remove the
11 ``NET_BW_EGR_KILOBIT_PER_SEC`` and/or ``NET_BW_IGR_KILOBIT_PER_SEC``
12 allocations related to the deleted port for the server `using the CLI`_.
