There are a couple interesting things going on here, and I haven't
quite untangled all of it. Basically the consoleauth_manager option
comes from nova.consoleauth.manager and when we don't import that
module the option isn't available to us. For some reason when running
`python -m subunit.run
nova.tests.integrated.test_servers.ServersTestV3.test_create_and_rebuild_server`
or `python -m testtools.run
nova.tests.integrated.test_servers.ServersTestV3.test_create_and_rebuild_server`
(this is what run_tests.sh -d does) nova.consoleauth.manager isn't
being imported, but when running `testr run
nova.tests.integrated.test_servers.ServersTestV3.test_create_and_rebuild_server`
it is. Not sure why there is a difference (possibly related to
discover?).I did manage to confirm that the attached patch mostly fixes the problem. It allows me to run the above commands out of the a tox built virtualenv, but not a run_tests.sh built virtualenv. This is the other piece of the puzzle that I haven't sorted yet. I do have a hunch it has to do with how oslo.config is installed. As a work around you can source the tox virtualenv then run run_tests.sh -N -d and that should work given the attached patch. I would submit a change to Gerrit but would like to understand more of what is going on first. If someone else groks this more please feel free to submit the fix instead. Clark
