Is your system up-to-date? Do you have lxcfs installed?

Here's what I have:
lxc 1.1.3-0ubuntu1~ubuntu14.04.1~ppa1
lxc-templates 1.1.3-0ubuntu1~ubuntu14.04.1~ppa1
lxcfs 0.9-0ubuntu1~ubuntu14.04.1~ppa1
linux-image-3.19.0-13-generic 3.19.0-13.13

I use kernel from vivid's repo (this was installed a long time ago),
you should be able to get similar version with
linux-generic-lts-vivid.

I tested both fedora and download template, both work fine (obviously
you should skip zfs-related parameters if you're not using zfs).

$ sudo lxc-create -B zfs --zfsroot data/lxc -n f22 -t fedora -- -R 22
$ sudo lxc-start -n f22;sudo lxc-console -n f22 -t 0
