title: Error importing vmdk files using ec2 developer tools
body: <p>Although vmdk disk format is supported by ec2-import-instance tool, every time I try to run the command on a vmdk file, I get the following error: </p>
  
  <pre><code>    ERROR: File uses unsupported compression algorithm 0
  </code></pre>
  
  <p>I invoke the tool in the following format:</p>
  
  <pre><code>    ec2-import-instance -f vmdk -o &lt;ACCESS KEY&gt; -w &lt;SECRET KEY&gt; &lt;VMDK file&gt;
  </code></pre>
  
  <p>I am using ec2 tools version 1.6.6.1.</p>
