We’re Surrounded By Spying Machines: What Can We Do About It? The hypervisor  isolates operating systems and applications from the underlying computer hardware so the host machine can run multiple virtual machines (VM) as guests that share the system's physical compute resources, such as processor cycles, memory space, network bandwidth and so on. virtualization approaches differ considerably in their security implications, proper applications, overheads, re-quirements,and threat models.Unfortunately,this simple fact is sometimes ignored when virtualization is used as a security component. Virtualization Security in Cloud Computing. Each guest OS or VM runs above the hypervisor. A type 2 hypervisor, also known as a hosted hypervisor, is installed on top of the host operating system, rather than sitting directly on top of the hardware as the type 1 hypervisor does. A virtualization architecture is a conceptual model specifying the arrangement and interrelationships of the particular components involved in delivering a virtual -- rather than physical -- version of something, such as an operating system (OS), a server, a storage device or network resources.
