Virtualization lets you run multiple virtual machines on a single physical machine, with each virtual machine sharing the resources of that one physical computer across multiple environments. Different virtual machines can run different operating systems and multiple applications on the same physical computer. While others are leaping aboard the virtualization bandwagon now, VMware is the market leader in virtualization.

In case of server consolidation, many small physical servers are replaced by one larger physical server, to increase the utilization of costly hardware resources such as CPU. Although hardware is consolidated, typically OS is not. Instead, each OS running on a physical server becomes converted to a distinct OS running inside a virtual machine. The large server can "host" many such "guest" virtual machines. This is known as Physical-to-Virtual (P2V) transformation.

Virtualization Improve the efficiency and availability of IT resources and applications through virtualization. Start by eliminating the old "one server, one application" model and run multiple virtual machines on each physical machine. It frees IT Administrators from spending so much time managing servers rather than innovating. About 70 of a typical IT budget in a non-virtualized datacenter goes towards just maintaining the existing Infrastructure, with little left for innovation.

A virtual machine can be more easily controlled and inspected from outside than a physical one, and its configuration is more flexible. This is very useful in kernel development and for teaching operating system courses.
