Public bug reported: The method ``TestNetworkBasicOps._setup_network_and_servers`` is used in several tempest tests. It creates a set of resources (network, servers, FIPs, etc). This method has a race condition when the config option "project_networks_reachable" if False (by default).
The server is created [1] but there is no connectivity test [2] (due to project_networks_reachable=False). The next step is to create a FIP [3]. Because we are not passing the port_id, we first retrieve all the VM ports [4]. The issue happens at [5]: the ports are created but are still down. An example of this can be seen in [5][6]: 1) The tempest test list the VM ports (only one in this case) but the port is down: https://paste.opendev.org/show/bSLi4joS6blqipbwa7Pq/ 2) The Neutron API finishes processing the port activation at the same time the port list call was made: https://paste.opendev.org/show/brRqntkQYdDoVeEqCeXF/ It is needed to add an active wait in the method ``get_server_port_id_and_ip4`` in order to wait all ports to be active.
