1/34

Using Virtualization in the

Classroom

WELLCOME TO EVERYBODY


2/34

Using Virtualization in the Classroom

Session Objectives

Define virtualization

Compare major virtualization programs

Define virtualization terminology

Discuss virtualization benefits

List requirements of virtualization Demonstrate the use of virtualization


3/34

What is Virtualization?

Not physically existing as such but made bysoftware (virtual)

Allows multiple operating systems to run onthe same physical computer at the same time

A software environment that emulates orattempt to match a computers hardware and

BIOS

Virtual machine software creates thisenvironment


4/34

Virtual Machine Software

In this presentation, I will discuss:

VMWare Workstation

Microsoft Virtual PC

Microsoft Hyper-V (briefly)

Other products not discussed

Parallels (Mac) and VMWare Fusion (Mac),VirtualBox (open source)


5/34

Virtualization Look Like VMWare

Running Windows server 2008 in

VMWare on a Windows xp Host

Running Windows vista in VMWare

on a Windows xp Host


6/34

Virtualization Look Like?

Live presentation


7/34

Running Windows 2003 in Microsoft

Virtual PC on a windows xp Host


Virtual PC on a windows xp Host


8/34


Virtual PC on a Vista Host

Live presentation


9/34

Virtualization Terminology

Host machine or host computer

The computer on which the virtual machine

software is installed (Virtual PC orVMWare, e.g.)

Virtual machine (VM) or Guest OS

The operating system that runs in virtual

machine software on the host computer Comprised primarily of a configuration file

and one or more virtual hard drive files


10/34

Virtualization Terminology (contd)

Virtual disk

One or more files that reside on the host

computer that make up the VMs hard disk Virtual network

The network configuration used by the VM

Options include: bridged, host only, NATand none

VMs behave like just another computer onthe network


11/34

Virtualization Terminology (contd)

Snapshot A partial copy of a VM at a particular

moment in time. Allows you to go back tothe VM at that particular state. Someprograms allow saving multiple snapshots.


12/34

Virtualization Benefits

Teach multiple operating systems

with a single host computer

Students can own their VM while havingminimal access to the host computer

Multiple VMs can run simultaneously onone host, networked and all (for example, a

client and a server or two servers)


13/34

Virtualization Benefits (contd)

Easy maintenance and testing

VM wont boot or got deleted or corrupted?

Copy another one. Snapshots allow unlimited try this

scenarios with a quick return to the systemstate before you tried it.


14/34


Run multiple versions of software

Teach Office 2007 while previewing Office

20xx by using two different VMs. For programming and database; write an

application in one version and easily teston another version


15/34


Isolate your OS from the campus

network and host computer

For programming and networking, runservices and write software which mightnormally interfere with the host computeror the campus network


16/34

Virtualization Requirements

Supported host operating system(Windows XP Pro, Vista, Server

2003/2008, Linux) Sufficient RAM on your host computer toaccommodate the host OS and the guestOSs you wish to run

Sufficient CPU power Sufficient hard drive space to

accommodate the stored VMs


17/34

Virtualization Recommendations

Minimum 1 GB RAM, 2+ GBrecommended for Vista and Server

2008 virtual machines Minimum 3.0 GHz P4, recommended

2.4+ GHz dual-core CPU

Separate hard drive (80 GB+) for theVMs


18/34

VMWare

VMWare was the first seriousvirtualization software

Around since mid-90s

The leader in server and desktopvirtualization


19/34

VMWare (contd)

Free products VMWare Player runs existing virtual

machines but cannot create a new VM VMWare Server can create and run VMs;

better suited for low-end server

applications


20/34

VMWare (contd)

VMWare Workstation

Flagship desktop product

Create and run VMs

Import VMs (including physical to virtual)

Has all of the bells and whistles including

unlimited snapshots, screen capture tocreate movies, jpgs

Costs: $189 retail


21/34

VMWare (contd)

VMWare Academic Alliance

Free to join fill out an application online

Unlimited VMWare Workstation licensesfor classroom use


22/34

VMWare Demonstration

Live presentation


23/34

VMWare VM on the Host Hard Drive


24/34


Virtual PC purchased by Microsoft around2005.

A basic desktop virtualization program No bells and whistles compared to

VMWare

Works well but not as flexible as VMWare

Current version is Virtual PC 2007

Free to download


25/34


Demonstration

Live presentation


26/34

Windows Server 2008 Hyper-V

Hyper-V is Microsofts newestvirtualization product

Meant to compete with VMWaresserver virtualization products

Excellent performance and reliability

Comes with Windows Server 2008 Server 2008 may become my next

desktop OS


27/34

Networking with Virtual Machines

Virtual Machine Networking Each VM has its own virtual network

adapter (NIC) Multiple network adapters are possible

Several modes for the virtual network

Bridged

NAT/Shared

Local/host only


28/34

Networking Modes

Bridged networking

The VM acts like any other computer on

the network Each VM network adapter gets its own IP

address and physical address

VMs can communicate with other VMs and

other physical computers on the networkincluding the Internet

Most flexible configuration


29/34

Networking Modes (contd)

Network Address Translation(NAT)/Shared Networking VM shares IP address with host computer

Host computer acts like router/firewall VM can access other computers on the

network including the Internet Other computers cannot access the VM

directly More secure configuration than bridged Wont work if the VM is to be a server


30/34

Networking Modes (contd)

Local/Host only networking

VMs can communicate with only other VMs(Virtual PC) or other VMs and the host PC(VMWare)

No communication with other physicalcomputers or the Internet

Ideal for doing activities that might interferewith the classroom network


31/34

VMWare/Virtual PC Comparison

VMWare Workstation Pros Better Linux support USB device support Multi-CPU support VM Teams Snapshots Better guest OS documentation

VMWare Workstation Cons $189 license without membership More features mean more complex user

interface


32/34

VMWare/Virtual PC Comparison (contd)

Virtual PC Pros

Free to download no membershiprequired

Simple user interface

Virtual PC Cons Skimpy (short) documentation

No USB device support

Fewer advanced features
