Virtualization for security

"Underneath, however, your virtualization software, coupled with the powerful networking ability of Linux, will make your life infinitely easier. If a you receive a phone call that a problem has developed on Bob's 'Windows computer' in legal, just use SSH to run a script that closes the virtualization software, blows away or backs up the damaged Windows image so that you can review it, and then copies a master copy of the Windows VM from your server. In just a few minutes Bob will be back up and running, and he'll never know how easy you have it."
