title: Hadoop virtual machine: can't connect
body: <p>I've downloaded and extracted the Hadoop virtual machine from <a href="http://developer.yahoo.com/blogs/hadoop/posts/2010/10/yahoo-cloud-virtual-machine-appliance/" rel="nofollow">http://developer.yahoo.com/blogs/hadoop/posts/2010/10/yahoo-cloud-virtual-machine-appliance/</a>.  I've started this up in VMWare Player on Windows 7, and logged in.  </p>
  
  <p>However, I can't then connect to the IP address shown for the VM through SSH, nor can I ping it.  What could be wrong?</p>
