Public bug reported: Currently the OVN driver initialization does not work with uWSGI because the initialization is different than eventlet and the post_fork_initialization() method [0] does not get called in the process.
The post_fork_initialization() method is the one responsible for a few things: * Starting the OVN database connections * Starting the maintenance task * Overwriting the agent and availability zone methods for OVN use [1] * Running the database synchronization script (in log or repair mode) [2] These steps would need to be factored out to adhere to the uWSGI initialization process.
