Abstract: Virtualization technology was invented to maximize the utilization of hardware resource by IBM in 1960s. Virtualization is the abstraction of the physical resources needed to complete a request and underlying hardware used to provide service. It splits up a physical machine into several virtual machines. A virtual machine can be defined as, “It is a software implementation of a computing environment in which an operating system or application can be installed and run. As hardware cost went down, the need for virtualization faded out. More recently, virtualization become important again to improve availability, security, cost reducing, reliability and flexibility. This paper describes Virtualization technology concept. And also a case study on live virtual machine migration is used to explain the points.
