[lxc-users] problems starting unprivileged container

[Mike Wright]

Hi all,

First post.  I think lxc is incredible. I've replaced all but one of my 
xen vms with containers and they have been rock solid.  It is now time 
to take away their privileges.  (sounds like being punished for being 
good ;)

Following Stéphane Graber's website LXC 1.0 [7/10] without success.

host: ubuntu-15.10 wily
lxc:  1.1.5
guest ubuntu-16.04 xenial pulled from jenkins

grep mike /etc/sub?id
   /etc/subgid:mike:100000:65536
   /etc/subuid:mike:100000:65536

~/.config/lxc/lxc.conf (empty)
~/.config/lxc/default.conf has lxc.network.{type,link,flags,hwaddr}
~/.local/share/lxc/XENIAL/{config,rootfs}
...XENIAL/config is standard config with correct full path to rootfs

I've made it this far:

As mike: lxc-start -n XENIAL -o log -l ERROR -F fails here:

conf.c:setup_ttydir_console:1551 - Device or resource busy - error 
unlinking /usr/lib/x86_64-linux-gnu/lxc/dev/console

That file didn't exist so I created it and tried again. Same failure.

Any idea how to proceed from here?

Thanks,
Mike Wright
