To use this book, you will need access to computers or servers that have hardware virtualization capabilities. Familiarity of Linux and accessing Linux servers using SSH is expected.
To set up the lab environment described at the end of Chapter 1, Installing OpenStack with Ansible, you will need to install and use Oracle’s VirtualBox and Vagrant. You can access details of how to set up your computer using VirtualBox and Vagrant by visiting https://github.com/OpenStackCookbook/vagrant-openstack.
There are additional recipes to get you started with the lab environment available at http://www.openstackcookbook.com. Refer to this website for information on installation of supporting software such as MariaDB/MySQL. More information can be found at http://bit.ly/OpenStackCookbookPreReqs.

There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: Configuration of the host’s networking, on a Ubuntu system, is performed by editing the /etc/network/interfaces file.A block of code is set as follows:
# Shared infrastructure parts
shared-infra_hosts:
controller-01:
ip: 172.29.236.110
controller-02:
ip: 172.29.236.111
controller-03:
ip: 172.29.236.112
# Compute Hosts
compute_hosts:
compute-01:
ip: 172.29.236.113
compute-02:
ip: 172.29.236.114When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
# Shared infrastructure parts shared-infra_hosts: controller-01: ip: 172.29.236.110 controller-02: ip: 172.29.236.111 controller-03: ip: 172.29.236.112 # Compute Hosts compute_hosts: compute-01: ip: 172.29.236.113 compute-02: ip: 172.29.236.114
Any command-line input or output is written as follows:
cd /opt/openstack-ansible/scripts
Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. Here is an example: "Next choose Advanced system settings from the menu on the left."
