As I verified my own local multi-node devstack dedicated H/W environment with varying commands, I initially came across the following error (which later was found to be misleading). https://ronaldbradford.com/blog/using-your-devstack-cloud-2016-04-05/ Tue, 05 Apr 2016 18:06:35 +0000 https://ronaldbradford.com/blog/using-your-devstack-cloud-2016-04-05/ You have setup and installed devstack . Now what! The Horizon UI will allow you to administer your running cloud from a web interface. We are not going to discuss the web UI in this post. https://ronaldbradford.com/blog/running-a-devstack-virtual-machine-with-limited-memory-2016-04-04/ Mon, 04 Apr 2016 15:50:07 +0000 https://ronaldbradford.com/blog/running-a-devstack-virtual-machine-with-limited-memory-2016-04-04/ If you have a system with only 4GB of RAM, you need to assign at least 2.5GB (2560M) to a virtual machine to install devstack . Even with this limited RAM there are times the devstack installation will fail. https://ronaldbradford.com/blog/downloading-and-installing-devstack-2016-04-02/ Sat, 02 Apr 2016 14:51:56 +0000 https://ronaldbradford.com/blog/downloading-and-installing-devstack-2016-04-02/ The following instructions assume you have a running Linux virtual machine that can support the installation of devstack to demonstrate a simple working OpenStack cloud. For more information about the preparation needed for this step, see these pre-requisite instructions: https://ronaldbradford.com/blog/setting-up-ubuntu-using-vagrant-2016-04-01/ Fri, 01 Apr 2016 20:04:55 +0000 https://ronaldbradford.com/blog/setting-up-ubuntu-using-vagrant-2016-04-01/ As discussed in Setting up an Ubuntu virtual machine using VirtualBox there are several other alternatives to defining an Ubuntu virtual machine. One of these alternatives is using Vagrant . https://ronaldbradford.com/blog/setting-up-centos-on-virtualbox-for-rdo-2016-04-01/ Fri, 01 Apr 2016 20:00:19 +0000 https://ronaldbradford.com/blog/setting-up-centos-on-virtualbox-for-rdo-2016-04-01/ Create a CentOS Virtual Machine (VM) NOTE: There are several different ways in creating a base VM CentOS image. These steps are the more manual approach, however they are provided for completeness in understanding varying options. https://ronaldbradford.com/blog/setting-up-ubuntu-on-virtualbox-for-devstack-2016-03-30/ Thu, 31 Mar 2016 00:58:06 +0000 https://ronaldbradford.com/blog/setting-up-ubuntu-on-virtualbox-for-devstack-2016-03-30/ As discussed , devstack enables a software developer to run a standalone minimal OpenStack cloud on a virtual machine (VM). In this tutorial we are going to step through the installation of an Ubuntu VM using VirtualBox manually. https://ronaldbradford.com/blog/virtualbox-networking-for-beginners-2016-03-30/ Wed, 30 Mar 2016 17:09:33 +0000 https://ronaldbradford.com/blog/virtualbox-networking-for-beginners-2016-03-30/ When using VirtualBox for my OpenStack development I always configure two network adapters for ease of development. The first is a NAT adapter that enables the guest VM connectivity to the Internet via the host. https://ronaldbradford.com/blog/installing-virtualbox-for-openstack-development-2016-03-30/ Wed, 30 Mar 2016 16:00:16 +0000 https://ronaldbradford.com/blog/installing-virtualbox-for-openstack-development-2016-03-30/ Download VirtualBox for your operating system VirtualBox is an open source virtualization product that will allow you to create virtual machines on a computer using Linux, Mac OS X or Windows. https://ronaldbradford.com/blog/installing-openstack-with-devstack-a-first-time-guide-2016-03-29/ Tue, 29 Mar 2016 14:42:21 +0000 https://ronaldbradford.com/blog/installing-openstack-with-devstack-a-first-time-guide-2016-03-29/ This guide will enable the reader to install a minimal OpenStack cloud using devstack for the first time. This guide will assume you have never installed virtualization software, used or configured devstack or even observed a running OpenStack cloud.
