  • System, processor, and method for incremental state save/restore on world switch in a virtual machine environment
    Patent number: 7937700
    Abstract: In one embodiment, a processor comprises a plurality of registers configured to store processor state and an execution core coupled to the registers. The execution core is configured, during a switch between processor execution of a guest and processor execution of a virtual machine manager (VMM) that controls the guest, to save only a portion of the processor state to a memory. In another embodiment, a method comprises switching from processor execution of a first one of a guest and a virtual machine manager (VMM) to processor execution of a second one of the guest and the VMM, wherein the VMM controls execution of the guest; and during the switching, the processor saving only a portion of a processor state to memory.
