Public bug reported:

In the nova queens 17.0.0.0b3 release, I'm seeing the following:

$ nova-manage api_db sync
/usr/lib/python2.7/dist-packages/oslo_db/sqlalchemy/enginefacade.py:332: NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
  exception.NotSupportedWarning

This is with Ubuntu packages, so I've not tried to recreate with pip-
installed packages.

In our /etc/nova/nova.conf use_tpool is commented out.

If I revert the following commit, the error goes away:
https://github.com/openstack/nova/commit/910008e2ef5dae1698ff7db791f4816c728c8bd0
