In hardware emulation, a piece of hardware imitates another, while in hardware virtualization, a hypervisor (a piece of software) imitates a particular piece of computer hardware or the entire computer. Hardware virtualization is not the same as hardware emulation. Instead of relying on the old model of “one server, one application” that leads to underutilized resources, virtual resources are dynamically applied to meet business needs without any excess fat" (ConsonusTech). "Ultimately, virtualization dramatically improves the efficiency and availability of resources and applications in an organization. Using virtualization, an enterprise can better manage updates and rapid changes to the operating system and applications without disrupting the user. This parallelism tends to reduce overhead costs and differs from multitasking, which involves running several programs on the same OS. With virtualization, several operating systems can be run in parallel on a single central processing unit (CPU). The usual goal of virtualization is to centralize administrative tasks while improving scalability and overall hardware-resource utilization. Hardware virtualization can be viewed as part of an overall trend in enterprise IT that includes autonomic computing, a scenario in which the IT environment will be able to manage itself based on perceived activity, and utility computing, in which computer processing power is seen as a utility that clients can pay for only as needed. It involves CPUs that provide support for virtualization in hardware, and other hardware components that help improve the performance of a guest environment. Hardware-assisted virtualization is a way of improving overall efficiency of virtualization. Guest programs need to be specifically modified to run in this environment. Paravirtualization – the guest apps are executed in their own isolated domains, as if they are running on a separate system, but a hardware environment is not simulated.
