The plugin should only be installed once. From the logs here is the only
place the plugin is being installed in the venv:


The rest of the references are just tox printing out the packages installed in
the venv before running a command.

It should be, devstack should be using the venv-tempest tox job to do venv
prep (like installling the plugins) and run commands (like running
tempest list-plugins for the log). This tox env is defined here:


It's sort of a hack, devstack is just using tox as venv manager for
setting up tempest. But, then we use tox in the runner (what used to be
devstack-gate) so this made sense.
