Hi Juss,
This link explains how to migrate from physical machine to virtual
(P2V), for Prowmox ve, which uses KVM (and openvz). But the techniques
explained here (based on clonezilla or System rescue CD) should apply to
KVM in a CentOS environnement too.
http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE
Basically, you copy the image file from the physical server, on the
network, with clonezilla or System Rescue CD, then you prepare a VM
using raw drives, and you replace the raw files by the image files of
the physical machine.
Notice that for a windows machine (no support for SCSI in KVM), you have
first to prepare the machine to use IDE drives, using the registry patch
mergeide.reg.
Hope that helps.
Alain
