METHOD FOR PROCESSING INPUT SIGNAL IN VIRTUAL MACHINE SYSTEM

摘要

A method for processing an input signal in a VMS(Virtual Machine System) is provided to offer the input signal to a VMM(Virtual Machine Monitor) as well as a plurality of OSs(Operating System) with one input device. An input signal processor a main VM checks over and transforms an input value of an input signal received from an input device when a user requests input through the input device(S102). A destination determiner determines a destination of the input signal by checking data transformed in the input signal processor(S104). The destination determiner requests operation to a VMM input transferor when the destination is a VMM(S106). The VMM input transferor checks the operation and requests the operation to the VMM(S110). The destination determiner restarts the operation by returning to the input signal processor of the main VM when the destination is the main VM, and the input signal processor transfers the data to an application program by transferring the data to a terminal driver(S112). The destination determiner transfers the data requests to a guest VM input transferor when the destination is a guest VM(S114). The guest VM input transferor transfers the data between the main and guest VM by transferring the data to a guest VM input receiver(S116).
