Introduction Virtualizations platforms have taken over the old local infrastructure and revolutionize the way we today design our work environment systems. New open source software have also open new doors for everyone to explore and use the new capabilities of this virtualization platforms.

Virtualization Virtualization presents a new relationship between hardware and software. In the past there has generally been a tight binding between hardware resources and the software packages that access those resources. For example, the hardware resources of a server the processor, memory, storage, and network connectivity have traditionally been available only to the operating system installed on that hardware. And operating systems have traditionally been written with an assumption that only one instance of an operating system will access those resources. Server virtualization on the x86 platform has been around now for more than a decade, yet many in the industry still consider it a "new" technology.
