    The nova-scheduler now can be run in native threading mode instead
    of with eventlet. This is an experimental feature that is disabled by
    default. Please test the native threading mode in pre-production before
    enabling it in production. If you do so please let us now how it went on
    the mailing list openstack-discuss@lists.openstack.org. Please read the
    `concurrency <https://docs.openstack.org/nova/latest/admin/concurrency.html>`__
    guide for more details.
