Boot into Xen 4.2 Domain-0 and create network bridge:

    $ sudo brctl addbr docker0

    $ rebar ling-build-image
    $ sudo xl create -c xen.config

Inside Ling start n2o_sample application:

    Ling 0.2.2 is here
    Started in 49438 us
    Erlang [ling-0.2.2]

    Eshell V5.10.2  (abort with ^G)
