  1. 1. Virtual Machine: A Computer Within Your Computer Created By Elaine Bryskar
  2. 2. Have You Ever??? <ul><li>Wanted to try another operating system? </li></ul><ul><li>Wanted to try evaluation software? </li></ul><ul><li>Wanted not worry about viruses on the Net? </li></ul>
  3. 3. Have You Ever??? <ul><li>Wanted to access something on another computer on your network? </li></ul><ul><li>Wanted a backup/recovery plan? </li></ul>
  4. 4. If You Answered Yes… <ul><li>Dreamer </li></ul><ul><li>Sense of Adventure </li></ul><ul><li>Don’t want to spend much money </li></ul>
  5. 5. Tasks from the Past PC Magazine February 2008 <ul><li>Overcome Vista’s incompatibility with older applications </li></ul><ul><ul><li>Such as games </li></ul></ul><ul><li>Run customized software that won’t work in today’s O/Ss </li></ul>
  6. 6. What Is Virtualization? <ul><li>Proven software technology </li></ul><ul><li>Runs multiple operating systems and multiple applications on the same computer at the same time </li></ul><ul><li>It is not dual-booting </li></ul><ul><li>Can be used by anyone who uses a computer </li></ul>
  7. 7. What Companies? <ul><li>Microsoft </li></ul><ul><li>IBM </li></ul><ul><li>Sun </li></ul><ul><li>HP </li></ul><ul><li>VMWare </li></ul>
  8. 8. What Is A Server? <ul><li>Allows multiple client machines to connect and use applications at the same time </li></ul>
  9. 9. What Is A Virtual Machine? <ul><li>Tightly isolated software container that can run its own operating system as if it were a physical computer </li></ul><ul><li>Behaves exactly like a physical computer </li></ul><ul><li>Contains its own virtual CPU, RAM, hard drive, and network interface card (NIC). </li></ul>
  10. 10. What Is A Virtual Machine? Without A Host O/S installed
  11. 11. Virtualization Approach <ul><li>VMWare inserts a thin layer of software directly on host operating system </li></ul><ul><li>This layer contains a virtual machine monitor that allocated resources dynamically </li></ul><ul><li>Allows multiple O/Ss to run concurrently on single physical computer </li></ul>
  12. 12. What Is A Virtual Machine? With a Host O/S installed <ul><ul><ul><ul><ul><li>CPU. Memory, NIC, Hard Drive </li></ul></ul></ul></ul></ul>Host Machine Guest Machines
  13. 13. How Is It Important To Me? <ul><li>Runs on any x86-based machine </li></ul><ul><li>Supports 64-bit O/Ss </li></ul><ul><li>Installs like an application, wizard-driven </li></ul><ul><li>Supports any VMWare or Microsoft virtual machine format </li></ul><ul><li>Supports multiprocessors </li></ul>
  14. 14. Why Is It Important To Me? <ul><li>Run Windows, Linux, Solaris, Ubuntu on same machine </li></ul><ul><li>Increase CPU utilization </li></ul><ul><li>Move virtual machines from one computer to another </li></ul><ul><ul><li>A VM is simply a file </li></ul></ul><ul><li>Capture the entire state of a VM and roll back to a prior state (Snapshot) </li></ul>
  15. 15. A Quick Review <ul><li>Compatibility: </li></ul><ul><ul><li>VMs are compatible with all standard x-86 machines </li></ul></ul><ul><li>Isolation: </li></ul><ul><ul><li>VMs are isolated from each other as if physically separated </li></ul></ul><ul><li>Encapsulation </li></ul><ul><ul><li>VMs encapsulate a complete computing environment </li></ul></ul><ul><li>Hardware independence: </li></ul><ul><ul><li>VMs run independently of underlying hardware </li></ul></ul>
  16. 16. A Quick Review <ul><li>Encapsulation makes VMs incredibly portable, easy to image </li></ul><ul><ul><li>Move and copy a VM image (file) just like any other software file </li></ul></ul><ul><li>Save VM to any standard data storage medium </li></ul><ul><ul><li>USB flash drive, another hard drive </li></ul></ul>
  17. 17. A Quick Review: Hardware Independence <ul><li>Configure VM with virtual components different from underlying hardware </li></ul><ul><ul><li>Move a VM from one kind of x86 machine to another without changing device drivers, OS, applications </li></ul></ul>
