Virtual machine definition computer11/7/2023 Also, its virtual disks can be moved from one type of storage to another without affecting the functioning of the virtual machine. VMs are isolated from the rest of the system, and multiple VMs can exist on a single piece of hardware, like a server. For example, a virtual machine can be moved from one physical host to another. A virtual machine (VM) is a virtual environment which functions as a virtual computer system with its own CPU, memory, network interface, and storage, created on a physical hardware system. The hypervisor provides physical hardware resources dynamically as needed and allows virtual machines to operate with a degree of independence from the underlying physical hardware. A virtual machine (or 'VM') is an emulated computer system created using software. vmdk extension holds the actual data stored by the VM:Ī virtual machine interacts with installed hardware through a thin layer of software called the hypervisor. vmx extension holds the configuration of the virtual machine and a file with the. Like a physical machine, a virtual machine has its own operating system (Windows, Linux, etc.), storage, networking, configuration settings, and software, and it. Virtual machines contain their own virtual hardware, including a virtual CPU, memory, hard disk, and network interface card, which look like physical hardware to the operating systems and applications.Įach VM consists of several types of files stored on a supported storage device. Virtual machine is a software implementation of a physical machine computer that works and executes analogically to it. What is a Virtual Machine (VM) For simplicity, think of a virtual machine, VM, as a 'computer made of software' that you can use to run any software youd run on a physical computer. A virtual machine can be defined as a software implementation of a computer that runs an operating system and executes programs just like a physical computer.
