I recently migrated to a new server (Ubuntu 14.04, dedicated, not virtual) and installed LXC 1.1.2. I had LXC set up on my previous server without any trouble but on the new server I'm consistently running into a problem with creating new unprivileged containers (as well as not being able to start migrated containers). With a newly-created user account, I consistently get the following error:

```
unshare: Operation not permitted
read pipe: Permission denied
lxc-create: lxccontainer.c: do_create_container_dir: 778 Failed to chown container dir
lxc-create: lxc_create.c: main: 274 Error creating container container-template-ubuntu-14.04-7

```

I followed some of the instructions here: <https://www.stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/> and poked around in `/proc/sys/kernel/` but this doesn't seem to have helped. I'm not sure what else I can try.
