The Orcas March CTP came in Virtual Image format and so the Beta-1 and Beta-2. For many people Virtual Machine is a new teminorlogy. In this post I am trying to help you understand what does this Virtual Machie mean.
While downloading the Virtual Machine files, you must have noticed that Orcas virtual machine requires Virtual PC 2004 SP1 or Virtual PC 2007 or Virtual Server 2005 R2 to work with downloaded files. Any of this software will help to achieve the concept of virtualization; as Orcas CTP/Beta comes in the form of virtual image, so virtualization concept is required to run the Orcas CTP/Beta.
Normally, computers run only one operating system at a time. Applications run on top of the operating system. The operating system uses device drivers to address the computer’s hardware. And the hardware includes every single piece of hardware for example, the mouse and keyboard, processor, memory, disk drives and drive controllers, video cards, network cards, sound card and other physical devices etc. In other words, a computer contains one set of devices, runs one operating system at a time, and has one set of applications on that operating system.
