title: How to fix "error in run: Failed to get machine "boot2docker-vm": machine does not exist"?
body: <p>Running <code>boot2docker</code> with the <code>start</code>|<code>info</code>|<code>stop</code>|<code>delete</code> arguments result in an error message:</p>
  
  <pre><code>snowch$ boot2docker start
  error in run: Failed to get machine "boot2docker-vm": machine does not exist    
  snowch$ boot2docker info
  error in run: Failed to get machine "boot2docker-vm": machine does not exist
  snowch$ boot2docker stop
  error in run: Failed to get machine "boot2docker-vm": machine does not exist
  snowch$ boot2docker delete
  error in run: Failed to get machine "boot2docker-vm": machine does not exist
  </code></pre>
  
  <p>The <code>init</code> error was slightly different</p>
  
  <pre><code>snowch$ boot2docker init
  error in run: Failed to initialize machine "boot2docker-vm": exit status 1
  </code></pre>
  
  <p>How can I fix this?</p>
