[lxc-users] Nested containers (cont'd)

[Nels Nelson]

Serge, et al,-

I was able to get the inner container started after I did two things.

First, I set this option in every container config:

    lxc.mount.auto = cgroup

Second, I create the directory /lib/var/lxc in each container in which I
created another nested container.

There is still a strange issue where starting a nested container with a
command like bash fails to put me into a functioning console.  The inner
container seems to work at first, but then hangs when a command is entered.

# lxc-create -n outer -t minimal
# lxc-start -n outer -- bash
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
bash-4.2# mkdir /var/lib/lxc
bash-4.2# lxc-create -n inner -t minimal
bash-4.2# lxc-start -n inner -- bash
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
bash-4.2# ls
<seems to hang><enter key>
lxc-start: Input/output error - failed to read
<seems to hang>

To work-around this, I had to start each container as a daemon, and without
a bash command.

# lxc-start -n outer -d
# lxc-attach -n outer -- bash
bash-4.2#

And then that weird "cannot set terminal process group (-1): Inappropriate
ioctl for device" error stopped showing up.
