title: EC2 instance reboot - instance ID does not exist
body: <p>I'm trying to reboot the remote instance:</p>
  
  <pre><code>ec2 = boto.connect_ec2(aws_access_key_id = key_id, aws_secret_access_key = access_key)
  ec2.reboot_instances([instanceId]) 
  </code></pre>
  
  <p>and got the error <code>The instance ID 'i-xxxxx' does not exist</code></p>
  
  <p>Looks like I should connect to region - how can I get this value if the instance ID is the only input param?</p>
