How Virtual Machines Provide Operating System Functions, Quiz & Worksheet - Kinds of Virtual Machines, Over 83,000 lessons in all major subjects, {{courseNav.course.mDynamicIntFields.lessonCount}}, The Java Virtual Machine: Definition, Structure & Memory Use, Computer Science 105: Introduction to Operating Systems, Biological and Biomedical - Definition, Examples & Avoidance. A Virtual Machine (or VM) is an emulated environment of a physical computer system that runs an operating system and applications. Server virtualization enables multiple operating systems to run on a single physical server as highly efficient virtual machines. In other words, creating a computer within a computer. A "virtual machine" was originally defined by Popek and Goldberg as "an efficient, isolated duplicate of a real computer machine." Xen Project is a free and open source virtual machine monitor (VMM), intended to serve as a type-1 hyperviser for multiple operating systems using the same hardware. Depending on the user's needs, system machines can be configured to perform as if they have a variety of different types of hardware.

A Type 2 hypervisor runs from the operating system of the host machine and provides a virtual operating system that still supports input/output (I/O) and memory management functions. A hypervisor, also known as a VM monitor, allows for multiple OS to run alongside each other on a single host machine. Server Virtualization. Sciences, Culinary Arts and Personal This application offers direct links to the host machine's hardware. Virtual hosts are able to share resources between multiple guests, or virtual machines, each with their own operating system instance. VM lifecycle management (or VMLM) is a documented set of processes that are used by administrators to manage the implementation, delivery, operation, and maintenance of virtual machines.
