This patch adds functional coverage for such resize. No extra code changes were needed on top of the migrate patches to make resize work. Now that the nova code supports the resize this patch removes the check from the API that rejected the operation. Note that in the spec [1] we agreed not to introduce new microversion for this change but treat it as a bugfix. The current change also makes it possible to accept the resize of these servers with _any_ microversion.

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.

See :nova-doc:`the admin guide <admin/port_with_resource_request.html>` for
|
|
administrative details.
