VMware Player is the easiest way to run multiple operating systems at the same time on your PC for free. VMware Player allows anyone to try new operating systems without rebooting your PC to switch between them. You can use it to safely try and test new software in an isolated environment on your PC. Very useful. VMware Player works well when you have a ready made virtual image you want to run, but when you want to create your own from scratch it has lacked the tools for that.
EasyVMX! at http://www.easyvmx.com/ is the simple and failsafe way to create complete virtual machines for VMware Player on the web. You can install any Windows, Linux, BSD or Solaris, and test LiveCDs in a safe environment. The original Virtual Machine Creator requires you to just fill four required configuration fields and you have your virual machine ready for download in seconds.
