Abstract

In one embodiment, a processor mode is provided for guest software. The processor mode enables the guest software to operate at a privilege level intended by the guest software. When the guest software attempts to perform an operation restricted by processor mode, the processor mode is exited to transfer control of the operation to a virtual-machine monitor, which runs outside this processor mode.
