Acceptance tests on bare module fails to initialize

[Rovanion]

When running bundle exec rake acceptance on a newly generated module the following output is produced:

$ bundle exec rake acceptance

You appear to be running Vagrant in a Bundler environment. Because
Vagrant should be run within installers (outside of Bundler), Vagrant
will assume that you're developing plugins and will change its behavior
in certain ways to better assist plugin development.

Changing the default HOST to the Ubuntu 14.04 or Fedora 20 defined in spec/acceptance/nodesets/ does not produce any output different than the one above, save for the name of the machine. The odd thing is that there seems to be a box for VirtualBox defined on the url specified in the log. So I don't know where to go from here.
