Converting a running physical machine to a KVM virtual machine » The Log Book of Manuel Kiessling. Let’s assume you have a physical machine running a Linux system, and you would like to convert this system into a virtual KVM/QEMU machine, keeping everything as close to the original as possible.
What follows is my approach. The first thing we need is a raw image file which mirrors the exact layout of the physical hard drive in our physical server. In our example scenario, the physical box has one hard drive at /dev/sda with a /boot Partition on /dev/sda2 and a physical LVM volume on /dev/sda3. This LVM volume houses a volume group with two logical volumes, one of them housing the root partition /, and the other one being unused. KVM-QEMU, QCOW2, QEMU-IMG and Snapshots. During the past few weeks I found myself doing lots of work with Windows VMs.
I finally started reading-up on the use of snapshots. The QCOW2 format is the most powerful format supported by KVM-QEMU. It does not pre-allocate disk space, it offers the ability to create snapshots and, later, you can create new images that use a previous image as a base to dramatically speed-up the setup of a future VM. In this article we will look at some of the advanced features available in the QCOW2 format through the QEMU Image tool. We will create a QCOW2 image, create snapshots within the image, create an image that is based on a backing file and copy an image to get rid of the reference to the backing file.

Although this may seem obvious, it is important to back up your files to an external backup medium before attempting a dual-boot installation (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose.

However, many companies no longer ship a physical disc but instead create a hidden partition on the hard drive in which the recovery-disk information is stored.
