Virtualization Mini-Glossary

Part of the Virtualization For Dummies Cheat Sheet

To help you get a better understanding and expand your knowledge of virtualization, get to know these useful terms and how they apply to virtualization and its process:

Bare metal: Virtualized servers in which the virtualization software is installed directly on the machine rather than on an operating system. Because it installs on the machine, it is said to reside on “bare metal.”

Client virtualization: Using virtualization to enable a client device (like a laptop) to support isolated operating environments. Client virtualization is often used to move workloads into isolated environments to reduce system administration requirements.

P2V: Shorthand for “physical to virtual.” P2V stands for the process of migrating systems from the physical hardware they originally ran on to virtual operating environments running in a virtualized environment.

Server virtualization: Running virtualization software on server machines in order to host multiple operating system environments on a single piece of hardware.

Storage virtualization: Using shared storage located on individual servers so that multiple servers can share a single storage device. Storage virtualization is often implemented after initial server virtualization efforts in order to centralize resources and reduce storage administration work.
