摘要： There is a need for providing the Xeon CPU with a two-level VM that is independent of VMM types and prevents the throughput from degrading when the OS operates the privilege register. A machine is provided with a processor and memory. The machine includes a first virtual machine manager for managing a virtual machine, a second virtual machine for managing an operating system, first management information, and second management information. The processor is provided with a register and a shadowing function. The machine uses a virtualization method. The first virtual machine manager detects a call from the second virtual machine manager. The first virtual machine manager enables the shadowing function when it is determined that an instruction for enabling the shadowing function caused the call.

摘要： The program attains compatibility of suppression of an overhead accompanying page exception handling in the case of operating a program whose amount of memory use is large on a virtual machine and suppression of the overhead accompanying page exception handling in the case of operating a first OS that has a function of making another OS run on a virtual machine. A VMM creates a shadow PT (Page Table) for prohibiting reading-writing of privileged memory that requires emulation of reading/writing by using a RSV-bit, and registers the shadow PT and the second PT that a second OS operating on the first OS has in an x86 compatible CPU equipped with page exception detecting function using two PT's. When a page exception occurs, the VMM refers to cause code of the page exception and, when a P field of the cause code is 0, determines immediately that emulation is unnecessary.

摘要： In a two-level virtual machine system having child VMMs operating on a parent VMM, the field update frequency of VMCS and VMCB which control a VMM assist function of a CPU is not uniform. A G field requiring reflection of emulation results is higher in update frequency than a C field. The semiconductor quantity and power dissipation caused by the assist function expansion tend to increase in the C field used for a condition decision as compared with the G field simply retaining a value because influence upon the CPU operation is greater in the C field. Therefore, events relating to the G field which is high in update frequency and less in increase of semiconductor quantity and power dissipation caused by the assist function expansion are coped with by the CPU with its assist function expanded. Events relating to the C field are coped with by the parent VMM.
摘要翻译：在具有在母VMM上操作的子VMM的两级虚拟机系统中，控制CPU的VMM辅助功能的VMCS和VMCB的现场更新频率不均匀。需要反映仿真结果的G场在更新频率上高于C场。由于辅助功能扩展引起的半导体量和功率耗散在用于条件判定的C字段中比G字段更容易增加，简单地保留值，因为在C字段中对CPU操作的影响更大。因此，通过辅助功能扩展的CPU来处理与由辅助功能扩展引起的更新频率高，半导体量增加和功率耗散小的G场有关的事件。有关C字段的事件由父VMM处理。

摘要： The present invention provides a machine system that enables the arbitration of IO accesses and band control based on the priority of virtual servers while curbing performance overhead during IO sharing among the virtual servers. A virtual machine system including a CPU, a memory, and an IO interface includes a hypervisor that generates plural virtual servers, and an IO controller that controls the IO interface. The IO controller includes: a DMA receiving unit that receives DMA requests from the IO interface; a decoder that decodes received DMA requests and locates the corresponding virtual servers; a DMA monitoring counter that monitors DMA processing status for each of the virtual servers; a threshold register set in advance for each of the virtual servers; and a priority deciding unit that compares the DMA monitoring counter and the value of the threshold register, and based on processing priority obtained as a result of the comparison, decides the priority of processing of the received DMA requests.
