This article describes why you need virtualization and list commonly used FOSS and proprietary Linux virtualization software.
VirtualBox is a virtual emulator like VMWare workstation. It has many of the features VMWare has, as well as some of its own.
I really like new Opensource VirtualBox from Sun. It is light on resources. Here is a quick tip – you can convert a VMware virtual machine (image) to a VirtualBox machine (image) using qemu-img utility, without reinstalling the GUEST operating system
You can easily start / stop / pause or take a snapshot from a shell prompt under a Linux / Windows host using vmrun command. This is useful if you do not want to run web interface for starting and/or stopping VMs.
Red Hat paid approximately $107 million in cash for Qumranet, a privately held company. Now, Red Hat positioned to deliver comprehensive, reliable and open virtualization to Linux and Windows servers and desktops.
Virtualization is the process of abstracting computing resources such that multiple operating system and application images can share a single physical server, bringing significant cost-of-ownership and manageability benefits. Through its Oracle VM product, Oracle offers scalable, low-cost server virtualization for heterogeneous applications.
Oracle VM is free server virtualization software that fully supports both Oracle and non-Oracle applications, and is three times more efficient than other server virtualization products.

Xen is a free open source software virtual machine monitor for Intel / PowerPC architectures. It is software that runs on a host operating system and allows several guest operating systems to be run on top of the host on the same computer hardware at the same time (just like VMWare software). Luckily Installing and managing XEN is quite easy under CentOS 5 Linux.
