But there is no need in fact to enable this service. I gave a try to LXC. There is unfortunately no better doc, and it seems I still have an issue with my cgroup configuration: gabx@hortensia ➤➤ ~ # lxc-start -n dahlia -d lxc-start: command get_cgroup failed to receive response gabx@hortensia ➤➤ ~ # lxc-ls dahlia The container is here and lxc see it. No idea where my cgroup issue comes from
