Microsoft® Virtual Server Classroom Setup Guide 1

Introducing Microsoft Virtual Server 2005 R2 SP1

This learning product is designed using Microsoft® Virtual Server 2005 R2 SP1. Virtual Server is a technology that allows a single computer to act as a host for one or more virtual machines. The virtual machines use a set of virtual devices that might or might not map to the physical hardware of the host computer.

The software that is installed onto the virtual machine is unmodified, full-version, retail software that operates exactly as it does when it is installed onto physical hardware.

The following definitions will help you with the remainder of this document:

• Virtual Server: Virtual Server is a server application that enables users to run a broad range of operating systems simultaneously on a single physical server. Virtual Server does not ship with this learning product, but it can be acquired from your MSDN® subscription, or it can be ordered or downloaded from: http://go.microsoft.com/fwlink/?LinkId=94481.

• Host Computer: The physical computer onto which an operating system and the Virtual Server application have been installed.

• Host Operating System: The operating system that is running on the physical computer.

• Virtual Machine: The computer that is running inside Virtual Server. In this document, “Virtual Server” refers to the application running on the host, while “virtual machine” refers to the guest operating system and any software that is running inside the Virtual Server application.

• Guest Operating System: The operating system that is running inside the virtual machine.

Page 4: 6423AF-En Implementing Managing Windows Server 2008 Clustering-Setupgd

2 6423A: Implementing and Managing Windows Server® 2008 Clustering

• Host Key: The key that is designated to take the place of the CTRL+ALT combination when logging on to Microsoft Windows®. By default, the host key is the ALT key on the right side of the keyboard. “HOST+DELETE” means RIGHT-ALT+DELETE. The host key can be changed once the Virtual Server is set up by going to Administrative Controls and clicking on Remote Control, then selecting Set Host Key.

By default, the virtual machine will run in a web application in the host computers.

Note: Pressing CTRL+ALT+DELETE while working with a virtual machine will display

the Windows Security dialog box for the host operating system. To close the dialog

box, press ESC. To access the Windows Security dialog box for a guest operating

system, press HOST+DELETE. Other than this difference, software on a virtual

machine behaves as it would behave on a physical computer.

You can configure virtual machines to communicate with the host computer, other virtual machines on the same host computer, other host computers, virtual machines on other host computers, other physical computers on the network, or any combination thereof.

The setup instructions that you will follow as part of this classroom setup guide configure Virtual Server and the Virtual Machines that run on the host. Changing any of the configuration settings may render the labs for this learning product unusable.

Page 5: 6423AF-En Implementing Managing Windows Server 2008 Clustering-Setupgd

Microsoft® Virtual Server Classroom Setup Guide 3

Setup Overview The host computers must be set up with a supported operating system. For more information, please visit the follow web site: http://go.microsoft.com/fwlink/?LinkId=116800&clcid=0x409. For the purposes of this learning product, it is not necessary for the host computers to be able to communicate with another network. However, allowing them to communicate with each other is recommended to make setup easier. The setup procedures below assume that the host computers can communicate with each other for setup purposes. You should note the administrator’s user name and password for the host computers, and provide this information to the instructor.

Important: It is highly recommended that you read the Partner Deployment Guide

on the Virtual Server page of the Microsoft Certified Trainer (MCT) secure site:

a. Shut down virtual machine and save changes: The machine is sent a shutdown command. After the machine has shut down in the background, the virtual machine is closed and all undo-disks are saved for use on the next start-up of the virtual machine.

b. Turn off and save changes: The machine is turned off, without shutting down, and all undo-disks are saved for use on the next start-up of the virtual machine.

c. Turn off machine and discard changes: The virtual machine is turned off. All changes to the virtual machine and all undo disks are discarded, returning the virtual machine to its original state.

Note: The Microsoft Learning Lab Launcher uses Undo drives to save changes, so if

these drives are deleted or moved, the Lab Launcher may not be able to restore

previously saved changes. Clicking the Reset button, as well as selecting the Turn off

machine and discard changes option, will delete the undo drives.

2. After the user has made their selection, they may click OK to close the virtual machine and apply their choices, or click Cancel to return to the VMRC and the virtual machine.
