Understanding Memory Virtualization in Operating Systems
Memory virtualization in operating systems involves mapping guest addresses to host addresses with an added level of indirection managed by the hypervisor. Virtualization extensions in x86 processors enhance efficiency by allowing safe execution of guest code in Ring 0 through supervisor mode. The a
