title: vagrant: a better to way to "reset" my guest vagrant vm's network?
body: <p>I am relatively new to vagrant but certainly liking it so far.</p>
  
  <p>One of the little problem I often face is that when my host machine's network goes down momentarily, it affects my connection to my vagrant guest vm.</p>
  
  <p>When my host machine's network comes back up again, I have to - on my host machine - run <code>vagrant halt</code> and then <code>vagrant up</code> in order to "reset" my guest vagrant vm's network so that it can connect to the internet once again.</p>
  
  <p>Is there a more "elegant" way of getting my vm's internet connection via my host machine's network to detect that the internet network connection is back up?</p>
