A virtual machine creates a virtual hard drive as well as a virtual computer, so you can install and run it from within another operating system. If you want to get rid of the virtualized (also known as the guest) operating system, just delete the virtual hard disk from the real (host) computer’s hard drive.

Interesting Article, I've actually

Interesting Article, I've actually been playing with this alot in my spare time. I find that installing a light operating system - ie basically minimum installation w/a gui, enabling SSH pop out 3 or 4 virtual machines about 20gig's a pop. Install them with tester OS's and services and see how long they last.. definatly has added alot of functionality to a network. I've recently attempted to install Kubuntu w/Vmware ESX 1.4 w/1 Guest of Kubuntu, and did about 5 Guest with in Guest OS's and they all sat on my network happy as could be running each other. I speculate that this could be a great way to build up a DMZ to appear to be a very large network w/o actually having to invest in the mutliple system types for peneration testing and such.

I would be Curious to actually Use one Virtual machine as a Virtual Router. Set up another Virtual machine to run as a N-IDS system for the private network created by the Virtual router. Run a few hosts with Web services/Ftp/media server all on one machine and see where the break point is. I mean of course the break point is RAM, but lets put it out there that you had 4GB of RAM sitting on a Board w/3.3GHZ+ Intel chip. Maybe food for thought in why this is so great?
