Abstract

In one embodiment, a processor comprises a redirect unit configured to detect a match of an instruction pointer (IP) in an IP redirect table, the IP corresponding to a guest instruction that the processor has intercepted, wherein the guest is executed under control of a virtual machine monitor (VMM), and wherein the redirect unit is configured to redirect instruction fetching by the processor to a routine identified in the IP redirect table instead of exiting to the VMM in response to the intercept of the guest instruction.
