Yes!. Thank you very much. The second link pointed to me into the right direction. In rabbitmq, user 'guest' can only connect via localhost. And I had configured his external IP.

So I did:

- change /etc/rabbitmq/rabbitmq-env.conf to 127.0.0.1
- change /etc/neutron/neutron.conf -> rabbit_host to 127.0.0.1
