Solution 1

This comment ❝The user id in the lxc instance should equal the user id in the host.❞ led me to my solution.

When I ran an IPython session as root, all functioned as expected. Duh!

ps -aux | grep python

root 1327 0.0 0.4 18956 13188 ? S 09:55 0:00 /usr/bin/python /srv/lwp/lwp.py

sudo lxc-info --name test-container

Name: test-container

State: STOPPED

sudo lxc-attach -n test-container functioned as expected.

Solution 2

For me, It was a privileges problem, I just executed the lxc-start command with sudo and It worked.

goal: create a isolated linux system on Ubuntu 14.04.2 LTS, 3.13.0-35-powerpc64-smp with an ultimate goal of running a hardened nginx server on this machine

After some research, I decided to try the recipe at http://www.unixmen.com/setting-multiple-isolated-linux-systems-containers-using-lxc-ubuntu-14-04/

I followed the instructions for installing lxc. I created a container with the following command:
```
lxc-create -n test-container -t ubuntu
```
However, when I tried to start the container
```
lxc-start -n test-container -d
```
I encountered an exception

lxc_container: lxc_start.c: main: 296 Executing '/sbin/init' with no configuration file may crash the host

My research using google searches did not turn up any answers that I could understand so I installed the LXC web panel from http://lxc-webpanel.github.io/tools/install.sh to get an alternative perspective.

The LXC web panel shows my container in the general overview. If I try to start my container 'test-container' the container runs. It has no IP address.

Even though my container is running via the LXC web console, I do not know how to access it for use.

I would appreciate help in starting the container from the command line so that I may continue to follow the recipe at http://www.unixmen.com/setting-multiple-isolated-linux-systems-containers-using-lxc-ubuntu-14-04/

Any alternate methods for running a hardened and secure nginx server on this machine would also be appreciated.
