Install and configure controller node for Ubuntu in nova, openstack Block Device Mapping is Invalid

[Dominik S]

Using this documentation I created Openstack. Unfortunately I gets an error when creating a new instance using Horizon.

(...)
WARNING keystoneauth.identity.generic.base Failed to discover available identity versions when contacting https://controller/identity. Attempting to parse version from URL.: keystoneauth1.exceptions.connection.ConnectFailure: Unable to establish connection to https://controller/identity: HTTPSConnectionPool(host='controller', port=443): Max retries exceeded with url: /identity (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f975b1f5c60>: Failed to establish a new connection: [Errno 111] ECONNREFUSED'))

- [X] This doc is inaccurate in this way:
# /etc/nova/nova.conf
[service_user]
(...)
auth_url = https://controller/identity
(...)

- [ ] This is a doc addition request.
- [X] I have a fix to the document that I can paste below including example: input and output.

If I am wrong I apologize but it seems to me that the address mentioned should be different as:
"http://controller:5000/" or "http://controller:5000/v3/"

In every place in this Guide is http and port 5000 for keystone hence I do not understand why it is different here.
