Hello! I'm following ( to set up OpenStack on some QEMU instances.

I'm confused by the auth_url format: some like 'http://controller:xxxx/v2.0' and some just like 'http://controller:xxx' and without v2.0. I found in Havana the 'v2.0' may be a bug in authenticating process. So I want to know what should I do?

I followed the intructions on that page exactly and I met with 'Unauthorized: Authentication required' error when Neutron tried to create port on my 'demo-net'. So the problem is critical to me.

Great thanks!

In my functioning Icehouse environment, auth_uri (NB: not auth_url) in /etc/neutron/neutron.conf does not contain the version as part of the URL. That is, I have:


On the other hand, in that same file, for configuring neutron/nova notifications, I have:

nova_admin_auth_url =

I have not experimented with the latter to see if it will do the right thing without the /v2.0 on the end, but with these settings exactly as shown here my environment is working correctly.
