Abstract
A data processing system facilitates virtual machine migration with direct physical access control. The illustrative data processing system comprises a software-programmable trap control associated with hardware registers of a computer that selectively vectors execution control of a virtual machine (VM) between a host and a guest. The data processing system further comprises a logic which is configured for execution on the computer that programs the trap control to enable the virtual machine to directly access the hardware registers when the virtual machine is not migrated and to revoke direct access of the hardware registers in preparation for virtual machine migration.
