"Thanks to two concepts driving the data center today—economy and green building—server virtualization is a pretty hot topic in the IT world. And lots of hardware and software vendors are offering solutions. Virtualization solutions have several benefits: you can easily migrate the virtual machine from one server to another, and the virtual machine can be provisioned as the clone image for reproducible usage, for example, during software development and testing.

"The process for achieving virtualized server consolidation depends on your starting point:

"If you are designing your system from scratch, you will implement virtualization from the ground up.

"If your system already exists in the physical state, you will migrate from the physical environment to the virtual one.

"I refer to the second process as physical-to-virtual migration, or PV2, and it's the subject of this article. Several methods, manual and automatic, are generally available to facilitate P2V migration. I'll talk about those methods and show you how to convert a physical server to a virtual machine using Clonezilla Live, a cloning-based solution.

"With Clonezilla Live, you first create a system image from the physical server, then use the boot CD to restore the image onto the virtual machine's hard disk. It's simple and fast, and it should be useful for software developers, system administrators, and support engineers who want to analyze a system copy while maintaining the original one unchanged (and avoid possible hardware mismatch challenges)."
