title: Disk validation failed for AWS Import/Export task
body: <p>I have been trying to convert a Docker image into a VMDK file for creating an AWS AMI using <a href="https://aws.amazon.com/ec2/vm-import/" rel="nofollow noreferrer">AWS's Import/Export</a>. For that:</p>
  
  <ol>
  <li><p>I have used <a href="http://mr.gy/blog/build-vm-image-with-docker.html" rel="nofollow noreferrer">this guide</a> for creating the <code>.img</code> file from my DockerFile.</p></li>
  <li><p>Now, I am using this command: <code>VBoxManage convertfromraw --format VMDK disk.img disk.vmdk</code> to convert my <code>.img</code> file to a <code>.vmdk</code> file, as IMG format, is unsupported by the AWS service.</p></li>
  </ol>
  
  <p>However, when I run the Import/Export service, it gives me this error: </p>
  
  <pre><code>"StatusMessage": "ClientError: Disk validation failed [Unsupported VMDK File Format]"
  </code></pre>
  
  <p>Is there anything which I did wrong in my conversion process?</p>
