Another sector where virtual machines are of great use is server virtualization. Logfile, NVRAM setting file, virtual disk file, and configuration file are some of the key files that make up a virtual machine. A host can have several virtual machines running at a specific time.
We can define a virtual machine as:Ī virtual machine is a computer file or software usually termed as a guest, or an image that is created within a computing environment called the host.Ī virtual machine is capable of performing tasks such as running applications and programs like a separate computer making them ideal for testing other operating systems like beta releases, creating operating system backups, and running software and applications. Therefore, implementing tasks such as accessing virus infected data and testing of operating systems are done using virtual machines.
Virtual machines are isolated from the rest of the system the software inside the virtual machine cannot tamper with the host computer. Virtual machines, on the other hand, are created to perform tasks that, if otherwise performed directly on the host environment, may prove to be risky.
