The 2.37 microversion adds support for automatic allocation of network
|
|
resources for a project when ``networks: auto`` is specified in a server
|
|
create request. If the project does not have any networks available to it
|
|
and the ``auto-allocated-topology`` API is available in the Neutron
|
|
networking service, Nova will call that API to allocate resources for the
|
|
project. There is some setup required in the deployment for the
|
|
``auto-allocated-topology`` API to work in Neutron. See the
|
|
`Additional features`_ section of the OpenStack Networking Guide
|
|
for more details for setting up this feature in Neutron.
|
|
|
|
.. note:: The API does not default to 'auto'. However, python-novaclient
|
|
will default to passing 'auto' for this microversion if no specific
|
|
network values are provided to the CLI.
|
|
|
|
.. note:: This feature is not available until all of the compute services
|
|
in the deployment are running Newton code. This is to avoid sending a
|
|
server create request to a Mitaka compute that can not understand a
|
|
network ID of 'auto' or 'none'. If this is the case, the API will treat
|
|
the request as if ``networks`` was not in the server create request body.
|
|
Once all computes are upgraded to Newton, a restart of the nova-api
|
|
service will be required to use this new feature.

|
The 2.37 microversion enforces the following:
|
|
|
|
* ``networks`` is required in the server create request body for the API.
|
|
Specifying ``networks: auto`` is similar to not requesting specific
|
|
networks when creating a server before 2.37.
|
|
* The ``uuid`` field in the ``networks`` object of a server create request
|
|
is now required to be in UUID format, it cannot be a random string. More
|
|
specifically, the API used to support a nic uuid with a "br-" prefix but
|
|
that is a legacy artifact which is no longer supported.
