Modify the relevant Vagrantfile (full-dev-platform) replacing the lines:
<pre><code>config.vm.box = "<i>box_name</i>" config.ssh.insert_key = true</code></pre>
with
<pre></code>config.vm.box = "<i>test_box_name</i>" config.vm.box = "<i>PathToBoxfile/Boxfilename</i>" config.ssh.insert_key = true</code></pre>
Launch the image as usual.
Node: Vagrant will cache boxes, you can force Vagrant to reload your box by running vagrant box remove test_box_name before launching your new image.
