![]() ![]() ![]() Virtual machine is a software abstraction that behaves as a complete hardware computer Machine, virtualization software and underlying hardware in Fig. ![]() Virtualization architecture typically consists of three layers in high level, virtual Systems, which address them as (real) disks. Storage subsystems can be virtualized by RAID controllers and storageĪrrays, which present the abstraction of multiple (virtual) disks to the operating Resource using multiplexing and give single logical view by aggregating multiple distinctįile systems. System (OS) can handle multiple concurrent applications over its limited hardware Space to applications, hiding and abstracting the physical memory space. Virtual memory is a technology to give illusion of larger and continuous memory Of indirection between the abstract and the concrete. The common theme is decoupling the logical from the physical, introducing a level Virtualization technology has been widely used in IT (Infor- mation Technology) industry. ![]()
