Similarly, Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. There are three areas of IT where virtualization is making head roads a) Network virtualization b) Storage virtualization c) Server virtualization Today, virtualization is in the forefront - helping businesses with scalability, security and management of their global IT infrastructure. Virtualization can host multiple guest operating systems. Each guest operating system runs in its own domain, Virtualization schedules virtual CPUs within the virtual machines to make the best use of the available physical CPUs. Each
