Abstract
A method and device may, in a computing system executing a operating system and having a mass storage device, rewrite the boot sector of the operating system on the storage device to execute a hypervisor operating system in a boot process, copy a file including the hypervisor kernel to a first sub-area on the storage device, copy software components of the hypervisor to a second sub-area on the storage device, boot to execute the hypervisor as an operating system, execute the operating system, retrieve information indicative of absolute mapping of sectors used by the operating system on the storage device, allocate for the sectors on a third sub-area of the mass storage device, perform a second boot to run the hypervisor as a host operating system, and execute the operating system as guest operating system.
