How Does Virtualization Work?
In essence, virtualization lets you transform hardware into software. Use software such as VMware ESX Server to transform or “virtualize” the hardware resources of an x86-based computer—including the CPU, RAM, hard disk and network controller to create a fully functional virtual machine that can run its own operating system and applications just like a “real” computer.
Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer.
