What Is Virtualization ?
• If you have ever divided your
hard drive into different
partitions than you probably
already know about
the virtualization.
• Is used with
OSes , Servers
Storage Devices
Or Network Resources.

Virtualization - A Concept
• Virtualization Is A way of Emulating hardware in
software.
• You will feel the Imaginary use of the hardware
rather then factual or realistic hardware.
• A virtualization system that partitions a single
physical “machine” into multiple virtual
machines.
• For Example,
▫ Dividing hard drive into logical portions.
▫ Mapping A Drive.
▫ Using FTP Servers.

Virtualization - A Concept
• Virtualization is way to run multiple
operating systems and user applications on
the same hardware
▫ E.g., run both Windows and
Linux on the same laptop.
• How is it different
from dual-boot?
▫ OSes run simultaneously
• The OSes are completely
isolated from each other

Uses of virtualization
• Server consolidation
▫ Run a web server and a mail server on the same
physical server
• Easier development
▫ Develop critical operating system components
(file system, disk driver) without affecting computer
stability
• Testing
▫ Testing a network product (e.g., a firewall) may
require tens of computers
▫ Try testing thoroughly a product at each pre-release
milestone
• Cloud computing

Types Of Virtualization
• Hardware
▫ Dividing a Part Of A hard wares and sharing resources via virtual
Machine.
• Desktop
▫ Cloud Computing & Server Virtualization.
• Software
▫ As a concept of Application Sharing.
• Memory
▫ Sharing Your virtual memory (RAM).
• Storage
▫ Hard drive storage as a virtual memory.
• Data
▫ Database virtualization, the decoupling of the database layer, which lies
between the storage and application layers within the application stack
over all.
• Network
▫ creation of a virtualized network addressing space within or across
network subnets.

Virtual Mashine Monitor
• A virtualization system
that partitions a single
physical “machine” into
multiple virtual machines.
• Terminology
▫ Host – the machine
and/or software on which
the VMM is implemented
▫ Guest – the OS which
executes under the
control of the VMM

Role Of Hardware Features
Virtual mashines
• Ubuntu , Android
Virtualization Software
• VirtualBox , Qemu
Host Operating System
• Windows 7

Hardware Intraction
• Processors
▫ More then one OS running on the mashine So
Much Powerful Processor Needed.
▫ Not Only Depends On
Clock Frequency
 Core i3 , Atom (1.87 GHz)
▫ Also Depends On
 RAM
 Cache Size

Hardware Intraction
• Hard Drive
▫ Where To Put The Virtual OS / Guest OS?
▫ Find The Minimum Requirement Of Your
 Guest OS.
 Host OS.
• Hardware Resource > HostOs H/w + GuestOS
H/w
• Minimum Requirments
 Win 7 - Minimum 8 GB HDD 512 MB RAM
 Vista - Minimum 8 GB HDD 1 GB RAM

Why We Need Virtualization ?
• Purchasing Many Machines For Different
purposes.(costly)
• Setting up them on Network and connecting
them (Adding the new machine or server).
▫ Thus no need of any installation process.
• No need to provide extra
▫ Electricity,
▫ Networking facility,
▫ Floor space.

Advantages Of Virtualization
• Can Create Multiple Mashine On Same Server
Which saves Money.
• Provides dynamic Guest Processor Frequency
Adjustment Which Make It Simple.
• Have Inbuilt Monitoring And Maintenance saves
time and space effort.
• Upgrading gets easier.
• Scalability(increase needs).
• Saving Software Costs.
• Resource sharing.

Various Virtual Mirrors
• Citrix XenServer
• IBM PowerVM
• iCore Virtual
• Red Hat KVM(Kernal-based Virtual Machine)
• Linux Vserver
• Microsoft Hyper-V
• Microsoft Windows Virtual PC
• Open VZ Linux
• Oracle Solaris Containers
• Oracle Virtual box
• Oracle VM Server
