Cannot create stack user: "Could not determine host ip address"

[Markus Zoeller (markus_z)]

Description
===========
The minimal settings of the `local.conf` of Devstack as described in
http://docs.openstack.org/developer/devstack/ are *not* enough to create
a stack user which is necessary/recommended for the whole stack process.

Steps to reproduce
==================

    $ git clone https://github.com/openstack-dev/devstack/
    $ cd devstack
    $ git checkout 4bfbc291eefd92d8b7885f36275b7ff541e067ab
    $ tools/create-stack-user.sh

Expected result
===============
The stack user should be created and this command should be possible:

    $ sudo su - stack

Actual result
=============
The stack user *doesn't* get created but an error message is shown:

    [Call Trace]
    tools/create-stack-user.sh:32:source
    /opt/stack/devstack/stackrc:780:die
    [ERROR] /opt/stack/devstack/stackrc:780 Could not determine host ip
    address. See local.conf for suggestions on setting HOST_IP.

Environment
===========
1. I use this vagrant setup to create my VM:
   https://github.com/markuszoeller/openstack/tree/master/scripts/vagrant/aio-U1404-VB

2. The devstack commit which introduced this is 4bfbc291eefd92
   If I use that commit's parent 7976f31 then the expected result is happening.

Logs & Configs

Without mentioning HOST_IP the same error is coming

Please note that the `local.conf` I used *has* HOST_IP set. See https://github.com/markuszoeller/openstack/blob/master/scripts/vagrant/aio-U1404-VB/files/local.conf.aio

Potentially related expired bug is https://bugs.launchpad.net/devstack/+bug/1013481

What I have done as a temporary solution is to modify stackrc and set HOST_IP=${HOST_IP:-10.0.2.15}

[Andreas Scheuring (andreas-scheuring)]

Root cause seems to be [1]

The issue is that the IPs that vagrant assigns by default are in the newly introduced private subnet range 10.0.0.0/22. Due to that devstack filters them out [2] and ends with no valid IP

You should be able to workaround that by either
* Configuring your Vagrantfile to use a different subnet range
config.vm.provider "virtualbox" do |vb|
   vb.customize ['modifyvm', :id, '--natnet1', '192.168.222.0/24']
end

or Configuring your local.conf to use a different subnet for FIXED_RANGE
FIXED_RANGE=10.0.0.0/24
