DEVICE FOR ADAPTING AN INPUT/OUTPUT INTERFACE UNDER VIRTUALIZATION ENVIRONMENT AND A METHOD THEREOF, PARTICULARLY WITH REGARD TO DYNAMICALLY ADAPTING THE INPUT/OUTPUT INTERFACE BETWEEN OPERATING SYSTEMS THAT SUPPORT DIFFERENT INPUT/OUTPUT DEVICES

摘要

PURPOSE: A device for adapting an input/output interface under virtualization environment and a method thereof are provided to enable a guest system to seamlessly offer a service in accordance with execution of an application according to input/output device capability of a host system.;CONSTITUTION: A VMM(Virtual Machine Monitor) layer(200) assigns overall control right of all resources to all guest operating systems by virtualization of hardware resources. A host system(300) hosts a back-end host device driver(310) on an upper part of the VMM layer. An input/output support unit(320) generates a virtual device interface in accordance with a type of an input/output device requested by a guest system(400). To provide a service in accordance with input/output capability of the guest system, the input/output support unit adapts an input/output interface of the guest system.;COPYRIGHT KIPO 2010
