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.
