Since Vagrant 1.1 has not been released yet and to avoid messing up with you
|

current Vagrant installation, I've vendored Vagrant's sources from the master
|

and made it available from [`vagrant-lxc`](bin/vagrant-lxc). So after installing
|

`vagrant-lxc` and adding the base box, create a `Vagrantfile` like the one below

and run `vagrant-lxc up --provider=lxc`:
