Balazs Gibizer 048250a4b7 Disable qos resize tempest test for nova-multi-cell job
It turned out that during the qos resize work we did not implemented
support of cross cell resize with qos ports. Tempest test coverage for
the resize and migrate is landed recently that made the nova-multi-cell
job to fail.

So this patch disables the qos resize and migrate tempest tests for the
nova-multi-cell job to unblock the gate.

Using ports with resource request

Starting from microversion 2.72 nova supports creating servers with neutron ports having resource request visible as a admin-only port attribute resource_request. For example a neutron port has resource request if it has a QoS minimum bandwidth rule attached. Deleting such servers or detaching such ports works since Stein version of nova without requiring any specific microversion.

However the following API operations are still not supported in nova:

  • Creating servers with neutron networks having QoS minimum bandwidth rule is not supported. The user needs to pre-create the port in that neutron network and create the server with the pre-created port.
  • Attaching Neutron ports and networks having QoS minimum bandwidth rule is not supported.

Also the following API operations are not supported in the 19.0.0 (Stein) version of nova:

  • Moving (resizing, migrating, live-migrating, evacuating, unshelving after shelve offload) servers with ports having resource request is not yet supported.

As of 20.0.0 (Train), nova supports cold migrating and resizing servers with neutron ports having resource requests if both the source and destination compute services are upgraded to 20.0.0 (Train) and the [upgrade_levels]/compute configuration does not prevent the computes from using the latest RPC version. However cross cell resize and cross cell migrate operations are still not supported with such ports.

As of 21.0.0 (Ussuri), nova supports evacuating, live migrating and unshelving servers with neutron ports having resource requests.

See the admin guide <admin/port_with_resource_request.html> for administrative details.
