Comment 18 for bug 1519641

Hello All,
I've found the problem and I'd like to share my solution.
Problem was in /etc/neutron/neutron.conf on controller and compute node!

Does not matter if you chose option 1 or option 2 networking there is misstake in documentation as well.

http://docs.openstack.org/liberty/install-guide-ubuntu/neutron-controller-install-option2.html
http://docs.openstack.org/liberty/install-guide-ubuntu/neutron-controller-install-option1.html

in section [keystone_authtoken] is Note:

"Comment out or remove any other options in the [keystone_authtoken] section."

THIS IS NOT TRUE!!

default neutron.conf contains following lines:

[keystone_authtoken]
auth_uri = http://127.0.0.1:35357/v2.0/
identity_uri = http://127.0.0.1:5000
admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%

I just removed first line "auth_uri" and used lines from documentation:

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = NEUTRON_PASS

I am able to create new instance now!
