摘要： A next-generation OS with a virtualization feature is executed as a user program on a first virtual processor by selecting, in response to a cause of a call for a host VMM, one of a guest status area (221) for executing a user program on a second virtual processor and a host status area (222) for executing the guest VMM, and by updating a guest status area (131) of a shadow VMCS for controlling a physical processor. Accordingly, without a decrease in performance of a virtual computer, the next-generation OS incorporating the virtualization feature is executed on a virtual server, and the next-generation OS and an existing OS are integrated on a single physical computer.

摘要： A method for making it possible for a virtualization software (VMM) to generally identify a PCI function of an interrupt requester presupposing the existing I/O devices based on the PCI express is provided. An interrupt relay circuit is provided between an I/O device based on the PCI express and a PCI express bridge. The interrupt relay circuit receives and relays an interrupt transaction issued by the I/O device, and records whether there is an interrupt request in an interrupt indicator in association with an interrupt identifier. A VMM 114 uniquely identifies an I/O device of interrupt requester by referring to the interrupt indicator 134.

摘要： A computer system with a physical computer having a physical processor, physical memory, virtual computer and virtual computer controller is disclosed. The virtual computer has its own processor and memory, which are virtual components that are provided by logically dividing the physical processor and memory, respectively. The virtual computer also has a page table storing a physical/virtual memory address correspondence relationship, and a protection object table for address management of a protected address space in the virtual memory. The controller includes a protection exception processing unit, protection exception save region, virtual/physical memory address converter, and instruction analyzer. Upon execution of protection exception processing, the controller compares an instruction address at which was generated the protection exception processing to an instruction address of protection exception information saved. If these are identical, a pseudo-instruction is used to execute the protection exception processing, thereby reducing the total processing amount required.

摘要： A method is provided which eliminates redundancy from the shadow PT operation performed by the VMM when the guest operating system running on a virtual machine updates a guest PT address. The VMM associates a plurality of shadow PTs with guest PTs and allocates their relation in memory. When it detects the update of a guest PT address, the VMM searches for a shadow PT corresponding to the updated guest PT. If the associated shadow PT exists, the VMM omits rewriting the shadow PT and registers the address of the shadow PT with the CPU. If the associated shadow PT does not exist, the VMM allocates a memory, creates a shadow PT, registers an address of the created shadow PT with the CPU, and records a relationship between the updated guest PT and the generated shadow PT.

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.
