Abstract: 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).

Abstract: A method for virtualizing a CPU is provided to stably and efficiently perform para-virtualization of an OS(Operating System), which is operated in a CPU having two CPU modes, in one CPU mode, and keep stability of a kernel and shorten a development time by minimizing modification of the kernel of a current OS. A virtualizer operates a plurality of guest OSs at the same time and executed in a privilege mode of a processor is provided. A non-privilege mode of the processor is divided into at least two virtual lower modes, which are hierarchically graded(S106,S108). A privilege command is transited to the virtualizer when the privilege command is generated in the virtual lower modes. The virtualizer transfers the privilege command to a hierarchical mode processing the privilege command among the virtual lower modes(S114), and the hierarchical mode processing the privilege command processes the privilege command, and the mode is kept or transited to the other virtual lower mode(S116).

Abstract: A method for booting a system is provided to improve entire booting speed of the system applying virtualization by initializing needed other OSs(Operating System) and service with a VMM(Virtual Machine Monitor) during initialization of a predetermined device and performing a predetermined application in a separate domain like the OS. A VMM is initialized when power is applied to a system(22). The VMM initializes a guest OS, and a device driver for interfacing at least one device with an application after the VMM is completely initialized(23). The VMM transfers a state of the device driver corresponding to the device, which is wanted to be operated by the guest OS, to the guest OS when the guest OS and the device driver are completely initialized(24).
