3. Operating System Virtualization
 Operating system–level virtualization is where
the kernel of an operating system allows for multiple
isolated user space instances, instead of just one.
 Such instances (often called containers virtualization
engines (VE), virtual private servers (VPS) or jails) may
look and feel like a real server from the point of view of
its owners and users.

6. Oracle VM VirtualBox
• It was created by innotek GmbH, purchased in 2008 by Sun
Microsystems, and now developed by Oracle.
• Supported host operating systems include Linux, Mac OS X, Windows
XP, Windows Vista, Windows 7, Windows 8, Solaris, and OpenSolaris;
there are also ports to FreeBSD and Genode.
Oracle VM VirtualBox is
a virtualization software package
or x86 and AMD64/Intel64-based
computers from Oracle Corporation as
part of its family of virtualization
products.

7. How to Install VirtualBox
 VirtualBox allows you to create virtual computers within
your physical computer, enabling you to run multiple
operating systems without dealing with dual booting or
hardware configurations. Setting up VirtualBox is very
straightforward, and most of your time will be spent
performing the standard operating system installation.
 Will first install VirtualBox
 Base OS is Windows 7
 Guest OS will be Ubuntu 14.04

9. Step 2: Installing VirtualBox

10. Step 3: Creating a Virtual Machine
When creating a virtual machine, you will need to install
the operating system just like you would on a regular
computer. This means that you will need the installation
discs for the operating system you want to install on the
virtual machine. If you download the ISO file for the
installation disc, you can burn it to a blank DVD, or
install it directly from the ISO file.

11. Click the "New" button. This will open the wizard that will guide you
through the process to create your first virtual machine.

12. Start the operating system installation. Once the virtual machine has been
configured, the wizard will close and you will be taken back to the VirtualBox main
window. Double-click your new machine in the left menu to start it up for the first time.

13. Set the amount of RAM. You will need to designate how much of your computer's RAM
will be allocated to your virtual machine. VirtualBox will automatically choose the
recommended minimum amount for the operating system you selected, but you can
increase or decrease this if you'd like.

14. Create a virtual hard drive. Your virtual machine will need a virtual hard drive in order to install the
operating system and any programs. This virtual hard drive is carved out of the free space available on
your computer. VirtualBox will set a recommended size based on the operating system, but you can set it
to whatever you'd like.

15. Install the operating system. After selecting the installation media, the
operating system installation will begin. Installation proceeds the same way
it would as if you were installing the operating system on a regular
computer. Copyright @ CBPGECJ

Part II Deploy OpenStack

19. I. Select a Linux Distribution
Only Ubuntu 14.04 (Trusty), Fedora 20 and CentOS/RHEL 6.5 are documented here. OpenStack also
runs and is packaged on other flavors of Linux such as OpenSUSE and Debian.
II. Install Selected OS
In order to correctly install all the dependencies, we assume a specific minimal version of the
supported distributions to make it as easy as possible. We recommend using a minimal install of
Ubuntu or Fedora server in a VM if this is your first time.
III. Download DevStack
git clone https://github.com/openstack-dev/devstack.gitThe devstack repo contains a script that
installs OpenStack and templates for configuration files
IV. Configure
We recommend at least a minimal configuration be set up.
V. Start the install
cd devstack; ./stack.sh

20. Node Configurations
Single Node- Only one server runs all nova-services
and also drives all the virtual machine instances
Multiple Nodes-Adding compute nodes to the
two node installation by simply installing Nova-compute on an
additional server and copying nova.conf file to the added node

administrators and users
