Embodiments of an invention for generating multiple address space identifiers per virtual machine to switch between protected micro-contexts are disclosed. In one embodiment, a method includes receiving an instruction requiring an address translation; initiating, in response to receiving the instruction, a page walk from a page table pointed to by the contents of a page table pointer storage location; finding, during the page walk, a transition entry; storing the address translation and one of a plurality of address source identifiers in a translation lookaside buffer, the one of the plurality of address source identifiers based on one of a plurality of a virtual partition identifiers, at least two of the plurality of virtual partition identifiers associated with one of a plurality of virtual machines; and re-initiating the page walk.
