Apparatus and method for guest and root register sharing in a virtual machine

摘要

A computer readable storage medium includes executable instructions to define a processor with guest mode control registers supporting guest mode operating behavior defined by guest context specified in the guest mode control registers. The guest mode control registers include a control bit to specify a guest access blocked register state and a shared register state. Root mode control registers support root mode operating behavior defined by root context specified in the root mode control registers. The root mode control registers include control bits to enable replicated register state access and shared register state access. The guest context and the root context support virtualization of hardware resources such that multiple operating systems supporting multiple applications are executed by the hardware resources.

1. A non-transitory computer readable storage medium, comprising executable instructions to define a processor with:
guest mode control registers supporting guest mode operating behavior defined by guest context specified in the guest mode control registers, wherein the guest mode control registers include a control bit to specify a guest access blocked register state and a shared register state; and root mode control registers supporting root mode operating behavior defined by root context specified in the root mode control registers, wherein the root mode control registers include control bits to enable replicated register state access and shared register state access; wherein the guest context and the root context support virtualization of hardware resources such that multiple operating systems supporting multiple applications are executed by the hardware resources.
