Hypervisor
Hypervisor definition
A hypervisor is a process that separates a computer’s operating system and applications from the underlying physical hardware. Usually done as software although embedded hypervisors can be created for things like mobile devices.
The hypervisor drives the concept of virtualization by allowing the physical host machine to operate multiple virtual machines as guests to help maximize the effective use of computing resources such as memory, network bandwidth and CPU cycles.
A hypervisor is a function that abstracts -- isolates -- operating systems (OSes) and applications from the underlying computer hardware. This abstraction allows the underlying host machine hardware to independently operate one or more virtual machines (VMs) as guests, allowing multiple guest VMs to effectively share the system's physical compute resources, such as processor cycles, memory space, network bandwidth and so on. A hypervisor is sometimes also called a virtual machine monitor (VMM).
A hypervisor would be used by someone who wants to consolidate space on a server or run multiple isolated applications on a single server.
Hypervisors are important to any system administrator or system operator because virtualization adds a crucial layer of management and control over the data center and enterprise environment. Staff members not only need to understand how the respective hypervisor works, but also how to operate supporting functionality such as VM configuration, migration and snapshots.
