Well if you are nova, neutron or cinder there is. http://docs.openstack.org/admin-guide/cli_set_quotas.html http://docs.openstack.org/admin-guide/dashboard_set_quotas.html > > They can be done as either extra commands >> (openstack dns quota set --foo bar) or as custom panels, but not >> the way other quotas get set. > > This has nothing to do with the big tent and everything to do with the > fact that the community at large has conflated quotas -- i.e. the limit > of a particular class of resource that a user or tenant can consume -- > with the usage of a particular class of resource.

(As a side note, keystone is the only place that this makes any sense, but we needed quotas a few years ago, and we had to do what everyone else had done at the time) > Usage information is necessarily the domain of the individual service > projects who must control allocation/consumption of resources under > their control.

The resources in tempest - thinks like setting up users / projects for running the tests, cleaning up resources post testing, checking if services are enabled / disabled in the cloud being tested, tagging tests (smoke, slow, etc) The are all used by projects using tempest for testing, and all of the above are only available to projects not using the plugin interface (the in tree tempest tests, in the openstack/tempest repository) >> Projects in tree in tempest >> are at a much better position, as any change to the internal >> API will have to be fixed before the gate merges, but other >> out of tree plugins are in a place where they can be broken at any >> point. > > An example here would be super-useful, since as mentioned above, Tempest > should only be validating public HTTP/REST APIs. > >> None of this is meant to single out projects, or teams.
