The resources needed by a port are expressed to nova via resource_request extending the port. If the port requested by nova boot has resource_request attribute, that means that placement must enforce the minimum bandwidth requirements.

features:
|
|
- The new extension ``port-resource-request`` adds the ``resource_request``
|
|
attribute to port responses. This attribute enables Neutron to communicate
|
|
to Nova resources needed by the port, such as physnet, VNIC type and
|
|
bandwidth. If the port requested by Nova boot has the ``resource_request``
|
|
attribute, then the Nova Scheduler will try to allocate the VM in a host
|
|
that can satisfy those requirements.
