title: Docker-machine resource limit
body: <p>I made docker-machine like below</p>
  
  <blockquote>
    <p>docker-machine create --driver virtualbox --virtualbox-cpu-count 2
    --virtualbox-memory 2048 default</p>
  </blockquote>
  
  <p>As I known, docker container is on this docker-machine host.
  I made some container on this docker-machine host, and somehow seems docker container use more resource than setting resource on docker-machine (actullay cpu).</p>
  
  <ol>
  <li>Is this possible? If so, What is actually do 'virtualbox-memory' and 'cpu-count'?</li>
  <li>Here is 'docker stats' output. Why is cpu usage more than 100%?
