title: Python Boto List Storage Devices Attached to Instance
body: <p>I'm using Python 2.7 and Boto.latest. </p>
  
  <p>I'm creating a dynamic inventory script and I would like to list the storage devices that are attached to each instance </p>
  
  <p>Example: </p>
  
  <pre><code>ID: i-3rblah
  Storage:
  -  /dev/sda 
  - /dev/sdb
  - /dev/sdc
  </code></pre>
  
  <p>Tried: </p>
  
  <pre><code>for reservation in reservations:
    for i in reservation.instances:
      volumes = conn.get_all_volumes(filters={'attachment.instance-id': i.id})
      print i.__dict__
      print volumes.__dict__ 
  </code></pre>
  
  <p>So I have some volume info, but not what the VolumeID is mapped to.</p>
