    摘要: In one embodiment, a method includes receiving a request to transition control to a virtual machine (VM) from a virtual machine monitor (VMM), calculating an offset value, receiving, during operation of the VM, a request for a current value of the timer, adjusting the current value of the timer based on the offset value, and providing the adjusted timer value to the VM.

    摘要: A processor, capable of operation in a host machine, including memory management logic to support a plurality of memory types for a physical memory access by the processor, and virtualization support logic to determine a host memory type for a reference to a memory location by a guest in a virtual machine executable on the processor based at least in part on a memory type field stored in an entry of an extended paging table of a virtualization support system of the host machine (extended memory type field), to determine a guest memory type for the reference to the memory location, and to determine an effective memory type based on at least one of the host memory type and the guest memory type.
