UNIFORM STORAGE DEVICE BY PARTIAL VIRTUALIZATION MACHINE

摘要

PURPOSE: A storage apparatus of a part virtualization machine is provided to improve the security of an input and output transaction by preventing access about the part virtualization machine. CONSTITUTION: An input and output port trap(402) captures an input and output request of a virtual input and output apparatus about an operating system. An input and output controller emulator(404) processes the input and output control request of the virtual input and output controller. An input and output device emulator(406) processes an input and output access request communicated with the virtual input and output device. A device driver(408) communicates with a physical input and output device based on the input and output control request.
