OpenStack Networking Essentials

By: James Denton, Derek Chamorro

Overview of this book

The OpenStack Networking API offers users the ability to create and manage both basic and complex network architectures that blend the virtual and physical network infrastructure. This book kicks off by describing various components of Openstack Neutron and installing Ubuntu OpenStack based on Canonical's process. Further on, you will use various methods to interface with Neutron to create and manage network resources. You will also get to grips with the relationship between ports, networks, and subnets through diagrams and explanations, and see how the logical components are implemented via plugins and agents. Moving forward, you will learn how virtual switches are implemented and how to build Neutron routers. You will also configure networks, subnets, and routers to provide connectivity to instances using simple examples. At the end, you will configure and manage security groups, and will observe how these rules translate to iptables rules on the host machines. By the end of the book, you will be able to build basic network architectures using Neutron networks and routers in no time.

Creating a virtual machine


To create a virtual machine, follow these steps:

  1. To create a virtual machine, click on the New icon in Oracle VM VirtualBox Manager:

  2. In the wizard, name the virtual machine, specify the operating system version (or something close to it), and click on Continue:

  3. In the next window, specify the amount of memory to allocate to the virtual machine and click on Continue. A minimum of 4096 MB of RAM is recommended.

  4. In the next window, click on Continue to create a virtual hard disk:

  5. A hard disk wizard will appear that will allow you to specify the virtual hard disk type. Choose the default VDI image type and click on Continue:

  6. The next step of the wizard allows you to specify whether the disk should grow dynamically up to the maximum size as data is added or be fully allocated at creation. Choose your preference and click on Continue:

  7. Lastly, provide a name for the virtual hard disk file and set the size of the disk to be created. For the examples in this book, a minimum of 12 GB is recommended.

  8. Click on the Create button to complete the creation of the virtual machine. The virtual machine will be listed in Oracle VM VirtualBox Manager:
