Abstract: A method and apparatus for providing an operating system based on a lightweight hypervisor. An electronic device includes a hypervisor, an operating system monitor, and a virtualized operating system. The hypervisor enables the virtualized operating system and a physical machine to share the resources of the physical machine. If the virtualized operating system accesses the resource, the operating system monitor determines whether to allow the access to the resource. Also, the operating system monitor verifies the integrity of the virtualized operating system and determines whether a threat to the virtualized operating system exists.
