Comment 4 for bug 1863137

Keeping this open to publicly track documentation task. (Also dropped into Trello.)

@ltetrel: to address the networking question ... I'm not sure why it's not working. I'm not aware of any limitations in MicroStack that would prevent you from using an external flat network, given that you configure it properly using the Openstack tooling.

Most of the MicroStack services log to the system journal, so you can go looking for errors that might help you troubleshoot with `journalctl -xe`, as well as getting an overview with `systemctl status snap.microstack.*`. There are a few MicroStack services that log to /var/snap/microstack/common/log, so I'd look in there for error messages as well.
