Virtualization A way To Begin with Virtual Reality… - Rahul Khanwani

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 HDD,RAM,Processor

Guest OS System Architructure Operating System Hardware Virtual Mashine Mirror App. A App. C App. B Operating System App. A App. B Guest OS App. C App. D

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

Example Of Virtual Mashine

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.
