=======================================
Quota class sets (os-quota-class-sets)
=======================================
Show, Create or Update the quotas for a Quota Class.
Nova supports implicit 'default' Quota Class only.
.. note::
Once a default limit is set via the ``default`` quota class via the API,
that takes precedence over any changes to that resource limit in the
configuration options. In other words, once you've changed things via
the API, you either have to keep those synchronized with the configuration
values or remove the default limit from the database manually as there is
no REST API for removing quota class values from the database.
For Example: If you updated default quotas for instances, to 20, but
didn't change ``quota_instances`` in your ``nova.conf``, you'd now
have default quota for instances as 20 for all projects.
If you then change ``quota_instances=5`` in nova.conf, but didn't
update the ``default`` quota class via the API, you'll still have
a default quota of 20 for instances regardless of ``nova.conf``.
Refer: `Quotas
<https://docs.openstack.org/nova/latest/user/quotas.html>`__
for more details.
.. warning::
There is a bug in the v2.1 API until microversion 2.49 and
the legacy v2 compatible API which does not return the
``server_groups`` and ``server_group_members`` quotas in
GET and PUT ``os-quota-class-sets`` API response, whereas the v2 API
used to return those keys in the API response.
There is workaround to get the ``server_groups`` and
``server_group_members`` quotas using
"List Default Quotas For Tenant" API in :ref:`os-quota-sets`
but that is per project quota.
This issue is fixed in microversion 2.50, here onwards
``server_groups`` and ``server_group_members`` keys are
returned in API response body.
