I am currently using Windows XP, but now am wanting to learn more about Virtualization software (such as VMWare, QEMU...) to run Linux (Kubuntu). VM = Virtualization machine Questions: 1) I figured out from the resources I found on the Internet, that if I want to run an operating system inside a VM. Must I create an disk image? or can I run an operating system from a partition inside the VM e.g. I have Ubuntu installed on another hard-drive or partition, and Windows on another hard drive. And from within Windows, I open VMWare or whatever and it will let me use Linux from that other harddrive WITHOUT first creating a disk image of the Linux installation... 2) If I DO create a disk image, when I run it inside VMWare will any changes made during the session be saved back to the image, or will it all be lost?
