title: How do I SSH into the boot2docker host vm that the Vagrant 1.6 Docker Provider sets up?
body: <p>I'm on OSX and I'd like to be able to SSH into the host vm in order to:</p>
  
  <ol>
  <li>Get access to a native docker environment. This facilitates understanding and debugging port forwarding issues. </li>
  <li>Vagrant rsync seems to leave a lot of unused synced directories that's eating up disk space that I'd like to recover. </li>
  </ol>
  
  <p>To be clear, this question is NOT about ssh:ing into the docker containers that the Vagrant provider creates, but into the intermediate boot2docker host vm that Vagrant creates. </p>
  
  <p>I know that a workaround is to not use the default boot2docker as the host vm (as explained in the answer <a href="https://stackoverflow.com/questions/23948831/forward-ports-from-boot2docker-using-the-vagrant-docker-provider">here</a>), but that's not what this question is about.</p>
