The hypervisor is a thin layer of software that separates the VMs from the host and interactively allocates resources as needed by the VM. Multiple Virtual Machines (VMs) or virtual computers are formed by dividing the hardware resources such as processors, servers, storage, etc. It is akin to multiple operating systems running concurrently on a single computer system. thus allowing software to replicate hardware functionality and resulting in the creation of a virtual system independent from the hardware. Virtualization is the technology that creates virtual versions of various resources such as the operating system, server, storage etc. To overcome these inefficiencies, it is important to understand what virtualization is and how to enable virtualization. This means that excess capacity available is not consumed resulting in increased operating and IT costs. The servers deployed by many IT firms are often not utilizing their capacity since the physical server is dedicated to a specific application.
