无法启动Openstack实例：尝试创建端口时“需要身份验证”

Question

I'm trying to deploy Openstack Icehouse on Ubuntu Server 14.04 by following the official document. But after Keystone\\Nova\\Neutron\\Glance were deployed, when I tried to launch a CirrOS instance by

nova boot -nic ... -image ... -flavor ...

, it failed.

The log in Nova client shows that:

• The Neutron client (Yes, it's neutron. I guess there are interactions between them in booting) tried to connect with Neutron server to create a port on tenant's network.
• But Neutron client set up the token-getting request using {username:neutron, password:REDACTED} to Keystone server and used that token to request for creating port to Neutron server.
• Finally, the Neutron Server decided that that's an authentication problem.

I'm sure that I requested to create instance using tenant 'demo' 's info($OS_TENANT_NAME, $OS_USERNAME, $OS_PASSWORD, $OS_AUTH_URL were properly set with 'demo''s value) by

source demoopenrc.sh

with demo's credential in that file.

Is that something wrong in the Neutron client's configuration or booting process? I paste a part of the neutron.conf here:

the Keystone setting

[keystone_authtoken]
auth_uri = http://controller:5000
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = neutron
admin_password = neutronpass
signing_dir = $state_path/keystone-signing

Since the Neutron client used 'neutron' user's credential for token getting, is there something wrong in this part?
