I want to do a live migration of my Fedora and Windows Server 2003 into raw disk image without restart the server or shut it down. (disk image is for virtualization purpose) Is there any open source software that I can use? I've heard of VMware Converter but it have to be moved to be virtualized in VMware Server ESXi or VMware Workstation.(I'll go for either Xen or KVM after the imaging) FYI, there's also database running on my server.
you cannot live migrate from physical to virtual hardware. What you should do is plan downtime for the VM, and when ready, image or back it up, then restore to the VM.
