摘要： A method is provided which eliminates redundancy from the shadow PT operation performed by the virtual machine monitor (VMM) when the guest operating system running on a virtual machine updates a guest page table (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 central processing unit (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： A VMM disables an interrupt interception flag on at least one CPU to execute, upon reception of an interrupt, an interrupt handler code of an OS, and enables the interrupt interception flag on the at least one CPU to execute, upon the reception of the interrupt, an emulator in the VMM. When, to a virtual machine, an I/O device is assigned in a dedicated form, and when the CPU is assigned while the interrupt interception is disabled, a destination of the interrupt from the physical I/O device is set to the corresponding CPU on which the interrupt interception is disabled. When, to the virtual machine, the I/O device is assigned in a shared form, or when the CPU is assigned while the interrupt interception is disabled, the destination of the interrupt from the physical I/O device is set to the corresponding CPU on which the interrupt interception is enabled.

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.
