PROBLEM TO BE SOLVED: To reduce overhead in achievement of sharing of I/O between virtual machines using a versatile I/O switch. SOLUTION: The system comprises a CPU module #0 including a plurality of CPU cores, an AS bridge 15 connected to the CPU cores, and a main storage accessible from the CPU cores or AS bridge 15, and AS switches SW0 and SW1 connecting the AS bridge 15 of the CPU module #0 to an I/O blade #5. The CPU module #0 has a hypervisor dividing the plurality of CPU cores and the main storage to a plurality of logical partitions, and the AS bridge 15 includes a virtual switch SWv1 a, when AS packets to be transmitted and received between the logical partitions and the I/O blade #5 are relayed, virtual route information set for each logical partition and route information from the AS bridge 15 to the I/O blade #5 to route information of the AS packets and switching the AS packets with the I/O blade #5 for each logical partition.
