    Part 1 Getting started
    1 Introducing OpenStack
    1.1 What is OpenStack?
    1.2 Understanding cloud computing and OpenStack
    1.2.1 Abstraction and the OpenStack API
    1.3 Relating OpenStack to the computational resources it controls
    1.3.1 OpenStack and hypervisors
    1.3.2 OpenStack and network services
    1.3.3 OpenStack and storage
    1.3.4 OpenStack and cloud terminology
    1.4 Introducing OpenStack components
    1.5 History of OpenStack
    1.6 Summary
    2 Taking an OpenStack test-drive
    2.1 What is DevStack?
    2.2 Deploying DevStack
    2.2.1 Creating the server
    2.2.2 Preparing the server environment
    2.2.3 Preparing DevStack
    2.2.4 Executing DevStack
    2.3 Using the OpenStack Dashboard
    2.3.1 Overview screen
    2.3.2 Access & Security screen
    2.3.3 Images & Snapshots screen
    2.3.4 Volumes screen
    2.3.5 Instances screen
    2.4 Accessing your first private cloud server
    2.4.1 Assigning a floating IP to an instance
    2.4.2 Permitting network traffic to your floating IP
    2.5 Summary
    1 Go to http://manning.com/bumgardner/ and download the VM image under Links.
    2 Make sure you have VirtualBox installed (this VM image was tested with version 4.3.30).
    3 Unzip the file devstack_icehouse_openstackinaction.
    4 Double click the dev_stack_icehouse_openstackinaction.vbox file (or use command-line arguments—see the VirtualBox docs for details).
    5 VirtualBox should now be launched, and you should see the devstack_icehouse_openstackinaction VM.
    6 Start the devstack_icehouse_openstackinaction VM.
    7 In the VM configuration, several ports are forwarded from the VM to your local host (IP=127.0.0.1). These ports include 2222 for SSH access to the VM and 8080 for access to the OpenStack Dashboard.
    8 Once the VM is started, log in to the VM using the sysop ID and password u$osuser01 (for example, ssh -u sysop@127.0.0.1 -p 2222).
    9 Once on the console, switch to the stack user: sudo -i -u stack.
    10 Execute the rejoin script: sudo /opt/devstack/rejoin-stack.sh.
    11 You’ll now see screens related to the output of OpenStack components. To select a specific screen, hold and release Control-+, and then press " (double- quotes). You’ll be presented with a list of screens.
