Public bug reported:

Whenever I run a command using 'nova-manage', I get an unrelated warning
followed by the output of my command:

    $ nova-manage vm list
    No handlers could be found for logger "oslo_config.cfg"
    instance   node            type       state      launched ...
    ....

Based on a quick bit of work with pdb, it seems this line is the
culprit:

https://github.com/openstack/oslo.config/blob/e208b500464f25930392c48c6748a48c752f1ccf/oslo_config/cfg.py#L774

We'd likely see this issue earlier/more often were a more verbose
logging configuration set for 'oslo_config', but this is the only
logging message typically issues by this . This is not a 'oslo_config'
issue but a 'nova' one: the logger just seems to be misconfigured.

There's also the issue of why this warning is occuring. I suspect out of
date configuration in devstack (which I'm using)
