<ul><br>I think the reason we probably missed this API was because of the really roundabout way that the information is provided in the response. It calls the quota engine driver [3] to get the class quotas. For the DB driver if nothing is overridden then nothing comes back here [4]. And the resources in the quota driver have a default property which is based on the config options [5]. So we'll return quotas on floating_ips and other proxy resources simply because of how abstract this all is.<br><br>To fix it, the os-quota-class-sets API would have to maintain a blacklist of resources to exclude from the response, like what we do for limits [6].<br><br>So yeah, I guess we'd need a new spec and microversion for this.<br><br>[1] <a href="https://review.openstack.org/#/c/411035/" target="_blank"><u><font color="#0000FF">https://review.openstack.org/#/c/411035/</font></u></a><br>[2] <a href="https://review.openstack.org/#/c/440815/" target="_blank"><u><font color="#0000FF">https://review.openstack.org/#/c/440815/</font></u></a><br>[3] <a href="https://github.com/openstack/nova/blob/15.0.0/nova/api/openstack/compute/quota_classes.py#L67" target="_blank"><u><font color="#0000FF">https://github.com/openstack/nova/blob/15.0.0/nova/api/openstack/compute/quota_classes.py#L67</font></u></a><br>[4] <a href="https://github.com/openstack/nova/blob/15.0.0/nova/quota.py#L92" target="_blank"><u><font color="#0000FF">https://github.com/openstack/nova/blob/15.0.0/nova/quota.py#L92</font></u></a><br>[5] <a href="https://github.com/openstack/nova/blob/15.0.0/nova/quota.py#L1069" target="_blank"><u><font color="#0000FF">https://github.com/openstack/nova/blob/15.0.0/nova/quota.py#L1069</font></u></a><br>[6] <a href="https://github.com/openstack/nova/blob/15.0.0/nova/api/openstack/compute/views/limits.py#L20" target="_blank"><u><font color="#0000FF">https://github.com/openstack/nova/blob/15.0.0/nova/api/openstack/compute/views/limits.py#L20</font></u></a><font color="#888888"><br><br>-- <br><br>Thanks,<br><br>Matt</font><br><br><br>__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)<br>Unsubscribe: <a href="http://OpenStack-dev-request@lists.openstack.org?subject:unsubscribe" target="_blank"><u><font color="#0000FF">OpenStack-dev-request@lists.openstack.org?subject:unsubscribe</font></u></a><u><font color="#0000FF"><br></font></u><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev" target="_blank"><u><font color="#0000FF">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</font></u></a></ul><tt><font size="2">__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)<br>Unsubscribe: OpenStack-dev-request@lists.openstack.org?subject:unsubscribe<br></font></tt><tt><font size="2"><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</a></font></tt><tt><font size="2"><br></font></tt><br><br><BR>
