Embodiments of apparatuses and methods for guest processes to access registers are disclosed. In one embodiment, an apparatus includes an interface to a first register, shadow logic, evaluation logic, and exit logic. The shadow logic is to, in response to a guest attempt to write data to the first register, cause the data to be written to a second register. The evaluation logic is to determine, based on the value of the data, whether to transfer control to a host in response to the guest attempt. The exit logic is to transfer control to the host after the data is written to the second register if the evaluation logic determines to transfer control.
