In one embodiment, a processor supports an alternate address space during execution of non-guest code (such as a minivisor or a virtual machine monitor (VMM)). The alternate address space may be the guest address space. An instruction in the minivisor/VMM may specify the alternate address space for a data access, permitting the minivisor/VMM to read guest memory state via the alternate address space. In another embodiment, a processor may implement a page table base address register dedicated for the minivisor's use. In still another embodiment, the minivisor may be implemented as a specified entry point in the VMM address space.
