Abstract
A processor includes guest mode control registers supporting guest mode operating behavior defined by guest context specified in the guest mode control registers. Root mode control registers support root mode operating behavior defined by root context specified in the root mode control registers. The guest context and the root context are simultaneously active to support virtualization of hardware resources such that multiple operating systems supporting multiple applications are executed by the hardware resources.
