Introduction
 Virtualization is the ability to run multiple
virtual machines on a single part of hardware.
The hardware runs software which enables you
to install multiple operating system which are
able to run simultaneously and independently,
in their own secure environment.
 Virtualization allows you to run multiple
operating system in virtual machines on a
single computer. Each copy of an operating
system is installed into a virtual machine.

Why used?
 The main objective of virtualization is to increased use of
hardware resource and to reduce management and resources
cost.
 Time, money and energy saved
 Testing and disaster recovery :  Once installed, a virtual machine
and its virtual hard disks can be considered a "container" that can
be arbitrarily frozen, copied, backed up, and transported between
hosts.
 High availability
 It improves scalability or flexibility to the network

Virtual machine
 A virtual machine is a collection of virtual hardware that creates a standard x86
or x64 PC environment that allows for the installation of a supported guest
operating system.
 Virtual machine are made up of
a)
b)
c)
d)
e)

virtual CPU
virtual Hard disk
RAM
virtual network Adapters
SCSI adapters, serial ports, parallel ports

etc
 Today’s the most well known and widely used virtualization software are
VMware
oracle virtual box
Microsoft virtual pc/Hyper-v (Microsoft os compatible
only)

Two types of virtualization
1) Host OS Based Virtualization (Type-2 Hypervisor
)
2) Bare-metal Hypervisor (Type-1 Hypervisor )
1) Host OS based virtualization
A host-based
virtualization systems requires an
operating system (such as window or
linux) to be installed on the
computer.

2) Bare-metal Hypervisor (Type-1 Hypervisor )
A bare-metal hypervisor system does
not require an operating system. The hypervisor
is the operating system.

NOTE:
Hypervisor : virtualization software
: also called virtual machine
manager is a program that allows multiple
operating system to share a single hardware
host.

Installation
Creating a Virtual Machine
Let’s begin by opening VMware Workstation from the Start menu.
Alternatively, you can type, “VMware” in the instant search field and select
VMware Workstation from the list of programs (Figure 1).

11

Next, click File | New | Virtual Machine. A wizard appears to create a new virtual
machine as shown in Figure 2.

12

Click “Next” and choose how you want to load Windows 7. You can load it from installation
media (DVD) or you can use an ISO image. Here we are using ISO image (Figure 3)

13

Next, select “Installer disc image file (ISO)” and browse to where your Windows 7 ISO
image resides. Click “Next” and enter the Windows 7 product key (Figure 4).

14

Click “Next”, and enter a virtual machine name and choose a location for your virtual machine
to reside. You can simply accept the defaults and move forward in the installation (Figure 5).

15

Click “Next” and accept (Figure 6) the default disk size of 40 GB. You can increase
or decrease this size as you see fit.

16

Click “Next” and you can customize your virtual machine hardware prior to
beginning the Windows 7 virtual machine Operating System (OS) load (Figure 7).
For example, you can add disks, serial ports, and printers. You
can also remove unnecessary hardware such as floppy drives and sound cards
(Figure 8).

17

Click OK and Finish and Windows 7 begins to load (Figure 9). Since you entered the
product key, VMware Workstation enters an “Easy Install” mode. Just sit back, relax, and
a Windows 7 virtual machine is installed.
