title: How can I mount ephemeral storage on a windows ec2 instance using boto?
body: <p>I have an AMI with Windows Server 2008 as an EBS root device.  I can start it an instance using boto and remote desktop into it, but I cannot seem to get it mount its ephemeral storage.  Is something wrong with my BlockDeviceMapping?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>import boto
  from boto.ec2.connection import EC2Connection
  conn = EC2Connection(mykey, mysecretkey)
  bdm = boto.ec2.blockdevicemapping.BlockDeviceMapping({'/dev/xvdb':'ephemeral0'})
  conn.run_instances(myami, key_name=mykeyname,security_groups=[mysecgroup],block_device_map=bdm)
  </code></pre>
  
  <p>When I run this code, an instance fires up and I can access, but I only see the root device mounted.</p>
