A hypervisor records error device information in a virtual PCI bridge, and makes error information in a device consistent with error information in a PCI bridge. A computer system includes a CPU, memory, and physical device PCI tree. In the memory, virtual machines capable of mutually independently acting, and a hypervisor that manages the virtual machines are existent. The physical device PCI tree includes physical bridges and devices. The physical bridge has a register in which information specifying the device is recorded. The virtual machine includes a virtual CPU, virtual memory, and virtual device PCI tree. The virtual device tree includes virtual bridges and virtual devices. The virtual bridge has a virtual memory space in which information specifying the virtual device in which an error has occurred is recorded. The hypervisor includes an interrupt handling program that is a virtual bridge modification program which modifies information in the virtual bridge. |
