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…
- Don’t want to spend much money
Tasks from the Past PC Magazine February 2008
- Overcome Vista’s incompatibility with older applications
- 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
- Can be used by anyone who uses a computer
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
- 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
Host Machine Guest Machines
- CPU. Memory, NIC, Hard Drive
How Is It Important To Me?
- Runs on any x86-based machine
- Installs like an application, wizard-driven
- Supports any VMWare or Microsoft virtual machine format
Why Is It Important To Me?
- Run Windows, Linux, Solaris, Ubuntu on same machine
- Move virtual machines from one computer to another
- Capture the entire state of a VM and roll back to a prior state (Snapshot)
A Quick Review
- VMs are compatible with all standard x-86 machines
- VMs are isolated from each other as if physically separated
- VMs encapsulate a complete computing environment
- 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 XP Media Center SP2
- VMWare Server VMs can run
Some Specifics: My Laptop Hardware
- 512 MB RAM for VM Server with Win2K installed
What Else Is On-Tap
- 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
- VMWare Server and VMWare Player
- Professional VMWare Server
- And, best of all, it’s FREE!
- Register (by giving an email address) and request as many serial numbers as you wish
