Appendix
A Step-by-Step Guide
to Using Server
Virtualization Software
Virtualization enables a school or student to get the most out of computer
resources. Schools can use virtualization to turn a single server-grade computer into a virtual
server that can host two, three, or more operating systems. For example, one computer can
house three virtual servers running Windows Server 2008. This capability saves the school
money on servers and enables more students to be able to work on their own operating systems.
Another capability of virtualization is the ability for a school or student to turn a single PC
into a virtual system on which to run another operating system—without having to alter the cur-
rent operating system running on the PC. A single computer lab PC or a student's home PC can
be turned into a host for Windows Server 2008. This is ideal, for example, when your textbook
comes with an evaluation copy of Windows Server 2008. You can install virtualization software
and then install Windows Server 2008 for completing hands-on projects and activities. You can
use your originally installed operating system, such as Windows XP or Vista, and also use
Windows Server 2008 in a virtual “window'' or “session,'' for example. When you are finished
learning Windows Server 2008, you simply remove the virtualization software and you're back
where you started with your original operating system.
This appendix is a step-by-step guide for turning a single computer into a virtual system
hosting one or more virtual machines. The main focus is on three popular virtualization systems
that are available free:
•
Microsoft Virtual PC
—Intended for a workstation-grade PC to host another operating
system, such as a Windows Server 2008 virtual machine
•
Microsoft Virtual Server
—Intended for a server-grade computer to host multiple virtual
machines, including Windows Server 2008 and other operating systems
•
VMware Server
—Intended for server-grade computers to host multiple virtual machines,
such as Windows Server 2008
