Comment # 1 on bug 1214845 from Chris

To mimic the minipc working system I installed this packages (with their
dependencies):
 - patterns-microos-cockpit
 - cockpit
 - cockpit-bridge
 - cockpit-kdump
 - cockpit-machines
 - cockpit-networkmanager
 - cockpit-packagekit
 - cockpit-pcp
 - cockpit-podman
 - cockpit-storaged
 - cockpit-system
 - cockpit-ws

A few commands to make it work:

# systemctl enable --now cockpit.socket
# systemctl restart cockpit.socket

I accessed to https://mylocalip:9090 with a regular user. I clicked over
"Limited access" to switch to administrative access. In the section of "Podman
containers" a message told me about enabling the podman service or something
similar, I agreed and now the LXC containers are working.

I don't know how it is related...
