Computer system, data-processing apparatus, bus-data transferring method, and computer-readable recording medium for transferring data flowing through system bus

摘要

This invention expands the scope of application of a pass-through technology in which a guest OS directly controls a remote device that is connected via a network. This data-processing apparatus is provided with a host OS that provides a virtual hardware environment to a guest OS that performs I/O processing with respect to a device implemented in a remote apparatus connected via a network. The host OS has a bus extension unit that traps I/O instructions issued by the guest OS, encapsulates the trapped I/O instructions, and delivers the encapsulated I/O instructions to the remote apparatus as network packets.
