Abstract
A processor includes a processor control register with a control flag that determines an operating mode of the processor. A pointer to a guest virtual machine context in a portion of a random access memory (RAM) is coupled to the processor. An execution control unit tests a first flag in the guest virtual machine context, the first flag to indicate whether the control flag is owned by a guest virtual machine associated with the guest virtual machine context. The execution control unit maintains the control flag in the processor control register if the control flag is owned by the guest virtual machine and maintains the control flag in a shadow location in the guest virtual machine context if the control flag is not owned by the guest virtual machine.
