I am a new user of Openstack on Ubuntu and I just re-installed OpenStack with NovaLXD on my machine. However, since the all lxd, lxc and my OS updated recently, I cannot use the way I usually did to start/stop OpenStack on Ubuntu now. After installation, I thought OpenStack is running because I could log into the dashboard and juju controller page, but when I typed "lxc list", I only saw

+------+-------+------+------+------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | // in previous versions, I can see all containers running here, so I can start/stop them by using "lxc start/stop"
+------+-------+------+------+------+-----------+

Hence, after installation, what I can do to stop OpenStack is shutting down my machine. Then I rebooted, I had no idea to run it again.

I also searched the release notes/help for lxc and lxd but I didn't find something useful for me.

Any hints will be appreciated! Thank you!
