    • Virtual Machine: A Computer Within Your Computer Created By Elaine Bryskar
    • Have You Ever???
      • Wanted to try another operating system?
      • Wanted to try evaluation software?
      • Wanted not worry about viruses on the Net?
    • Have You Ever???
      • Wanted to access something on another computer on your network?
      • Wanted a backup/recovery plan?
    • If You Answered Yes…
      • Dreamer
      • Sense of Adventure
      • Don’t want to spend much money
    • Tasks from the Past PC Magazine February 2008
      • Overcome Vista’s incompatibility with older applications
        • Such as games
      • Run customized software that won’t work in today’s O/Ss
    • What Is Virtualization?
      • Proven software technology
      • Runs multiple operating systems and multiple applications on the same computer at the same time
      • It is not dual-booting
      • Can be used by anyone who uses a computer
    • What Companies?
      • Microsoft
      • IBM
      • Sun
      • HP
      • VMWare
    • What Is A Server?
      • Allows multiple client machines to connect and use applications at the same time
    • What Is A Virtual Machine?
      • Tightly isolated software container that can run its own operating system as if it were a physical computer
      • Behaves exactly like a physical computer
      • Contains its own virtual CPU, RAM, hard drive, and network interface card (NIC).
    • What Is A Virtual Machine? Without A Host O/S installed
    • Virtualization Approach
      • VMWare inserts a thin layer of software directly on host operating system
      • This layer contains a virtual machine monitor that allocated resources dynamically
      • Allows multiple O/Ss to run concurrently on single physical computer
    • What Is A Virtual Machine? With a Host O/S installed
              • CPU. Memory, NIC, Hard Drive
      Host Machine Guest Machines
    • How Is It Important To Me?
      • Runs on any x86-based machine
      • Supports 64-bit O/Ss
      • Installs like an application, wizard-driven
      • Supports any VMWare or Microsoft virtual machine format
      • Supports multiprocessors
    • Why Is It Important To Me?
      • Run Windows, Linux, Solaris, Ubuntu on same machine
      • Increase CPU utilization
      • Move virtual machines from one computer to another
        • A VM is simply a file
      • Capture the entire state of a VM and roll back to a prior state (Snapshot)
    • A Quick Review
      • Compatibility:
        • VMs are compatible with all standard x-86 machines
      • Isolation:
        • VMs are isolated from each other as if physically separated
      • Encapsulation
        • VMs encapsulate a complete computing environment
      • Hardware independence:
        • VMs run independently of underlying hardware
    • A Quick Review
      • Encapsulation makes VMs incredibly portable, easy to image
        • Move and copy a VM image (file) just like any other software file
      • Save VM to any standard data storage medium
        • USB flash drive, another hard drive
    • A Quick Review: Hardware Independence
      • Configure VM with virtual components different from underlying hardware
        • Move a VM from one kind of x86 machine to another without changing device drivers, OS, applications
    • Some Specifics: Software
      • Windows Operating System
        • Windows XP Media Center SP2
        • Windows 2000 Server
        • Windows Server 2003
      • VMWare Server VMs can run
        • Windows 3.1 – Vista
        • Ubuntu
        • Linux
        • DOS
    • Some Specifics: My Laptop Hardware
      • RAM: 1.49 GB
      • CPU: 1.73 MHz
      • Hard Drive: 111GB
      • Allocated
        • 512 MB RAM for VM Server with Win2K installed
        • 8 GB Hard Drive Space
    • My Desktop
    • My Desktop
    • What Else Is On-Tap
      • Browser Appliance add-on
      • Protect against viruses, adware, other malware with Firefox in a VM. Leverages VM isolation to prevent downloaded malware from propagating to desktop
      • Take a snapshot before browsing and wipe it away
      • It’s free but other Appliances are not
    • Research Information
      • VMWare Server and VMWare Player
