COMPUTER SYSTEM, DATA-PROCESSING APPARATUS, BUS-DATA TRANSFERRING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

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.

主权项

1. A data-processing apparatus providing a virtual hardware environment for a guest OS comprising:
extender configured to trap an I/O instruction issued by a guest OS, encapsulate the trapped I/O instruction, and send out the encapsulated I/O instruction as a network packet to the remote apparatus, the guest OS performing I/O processing with a device implemented in a remote apparatus connected via a network.
