Cannot find any containers in lxc (Openstack with Novalxd)

[Adam Chen]

Before I updated lxc, lxd and Ubuntu to the latest version, I can run each container of Openstack by "lxc start container-name " and I also can check the container names by "lxc list".

After I updated them all, I re-installed Openstack by the tutorial here(https://askubuntu.com/questions/955728/conjure-up-unable-to-deploy-openstack-cloud-on-lxd-configuration-ubuntu-16-04l). After installation, I thought OpenStack is running because I could log into the dashboard and juju controller page. I also could use "juju status" to find out their infos. However I tried to type "lxc list" and the only output was

+------+-------+------+------+------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+------+-------+------+------+------+-----------+
I tried to use "lxd shutdown" or other commands but none of them can shut down OpenStack. I had to reboot and found that I have no idea to start them again because "lxc start" doesn't work since there's nothing in "lxc list"
So, where are containers? How could I can start/stop them again?

Any help will be appreciated! Thank you!

I originally posted this issue on GitHub of lxc. (https://github.com/lxc/lxc/issues/2296)
The guy told me that I have to post the issue here.

I can't reproduce this with the latest bionic image. e.g. lxc list gives:
