Title:
  error when connecting to metadata service with neutron

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  When configured with neutron, I'm able to start a cirros instance and
  ssh to it, but it fails to connect to the metadata service. From the
  cirros console:

  checking http://169.254.169.254/2009-04-04/instance-id
  failed 1/20: up 9.25. iid had '<html>
   <head>
    <title>500 Internal Server Error</title>
   </head>
   <body>
    <h1>500 Internal Server Error</h1>
    Remote metadata server experienced an internal server error.<br /><br />

  From /opt/stack/logs/screen-q-l3.log:

  It looks like devstack is not setting the keystone authentication options in /etc/neutron/metadata_agent.ini. Here are some lines from that file in my deployment:

  
  # The Neutron user information for accessing the Neutron API.
  auth_url = http://localhost:35357/v2.0
  auth_region = RegionOne
  admin_tenant_name = %SERVICE_TENANT_NAME%
  admin_user = %SERVICE_USER%
  admin_password = %SERVICE_PASSWORD%

  
  Here's what my localrc looks like:

  
  # Default passwords
  ADMIN_PASSWORD=password
  MYSQL_PASSWORD=password
  RABBIT_PASSWORD=password
  SERVICE_PASSWORD=password
  SERVICE_TOKEN=password
