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>

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

I'm running ubuntu 12.04 inside of VirtualBox.
