Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization began in 1960s mainframe computers as a method of logically dividing the system resources provided by mainframes between different applications.
Since then, the meaning of the term has broadened.[1] Hardware virtualization[edit] Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. In hardware virtualization, the host machine is the actual machine on which the virtualization takes place, and the guest machine is the virtual machine.
Different types of hardware virtualization include: Snapshots[edit] Migration[edit] Failover[edit] Software.
