Abstract: Embodiments of an invention for generating multiple address space identifiers per virtual machine to switch between protected micro-contexts are disclosed. In one embodiment, an apparatus includes privileged mode logic, an interface, and memory management logic. The privileged mode logic is to transfer control of the processor among a plurality of virtual machines. The interface is to perform a transaction to fetch information from a memory. The memory management logic is to translate an untranslated address to a memory address. The memory management logic includes a storage location, a series of translation stages, determination logic, and a translation lookaside buffer. The storage location is to store an address of a data structure for the first translation stage. Each of the translation stages includes translation logic to find an entry in a data structure based on a portion of the untranslated address.
