Virtual Machine – Solution to run Multiple Operating System

The present study deals with the Development of Multiple Operating Systems on the same Computer. This means that one can keep<br>more than two operating Systems on the same Computer (e. g. if one has latest version of Microsoft windows vista it is possible to have older<br>version of Microsoft Windows XP on the same Computer) and simultaneously can carry on the development of multiple application software<br>with different versions by installing Virtual PC 2007. In the IT world Virtualization refers to the use of virtualization software that allows the<br>physical hardware of a single PC to run multiple Operating Systems simultaneously in Virtual Machines. The virtualization software simulates<br>enough hardware to create an environment that allows an unmodified guest operating system (the one running inside a Virtual machine) to be in<br>isolation on a host operating system (the one running physical computer system). This setup is very useful particularly, in a given scenario where<br>most of the educational institutions simultaneously offer different courses and different levels of a course syllabus, with limited resources at its<br>disposal. If we need to teach advanced version of operating systems like “Microsoft Windows Vista”, along with application software<br>“Microsoft Office 2010” and “Microsoft Internet Explorer 7” and at the same time, older version of Operating System like, “Microsoft Windows<br>XP”, along with application software, “Microsoft Office 2003” and “Microsoft Internet Explorer 6” as another subject for a different class in the<br>same Computer lab. This can be done by installing different operating system on different partitions of the disk but such a setup requires<br>rebooting the computer every time the user intends to shift from one operating system to another. This problem can very-well be solved by<br>Virtual Machine. User can load two Operating systems like, Microsoft windows Vista and Microsoft Windows XP and then can install<br>Microsoft office 2010 on the first Virtual Machine and Microsoft office 2003 on the second. Just like all application software click the icon of<br>virtual machine operating system on desktop of windows 7 or select from start button to switch over to the other operating system as well as<br>Application software. The study deals with how to create, copy, and configure virtual machines. Microsoft Virtual PC 2007 to run multiple<br>operating systems at the same time on the same physical computer.
