title: Docker Machine - generic driver does not support start
body: <p>I try to use <code>Docker Machine</code> on a host and have got following error:</p>
  
  <blockquote>
    <p>generic driver does not support start</p>
  </blockquote>
  
  <p>This script is working perfectly on another hosts. I have looked into the problem, but haven't find other that this: <a href="https://github.com/docker/machine/blob/master/drivers/generic/generic.go" rel="nofollow">https://github.com/docker/machine/blob/master/drivers/generic/generic.go</a>
  Which preferences should I check to resolve this problem?</p>
