Apparatus and method for virtualizing input/output devices using shared memory in host-based mobile terminal virtualization environment

An apparatus for virtualizing Input/Ouptut (I/O) devices, comprising:

• a hardware device control unit configured to control I/O devices of a terminal;
• a guest Operating System (OS) unit configured to run a guest OS for running an application program via a virtual machine;
• a virtual machine monitor unit configured to include shared memory for transferring I/O data and an event channel for transferring events between OSs, to store an instruction and data, corresponding to an I/O request signal, in the shared memory when the I/O request signal is received from the guest OS unit, and to transfer the stored instruction and the data to a host OS via the event channel;
• and
• a host OS unit configured to perform an operation of assigning the shared memory to the virtual machine monitor unit, an operation of generating the event channel, and an operation corresponding to the I/O instruction via the hardware device control unit when the I/O instruction is received via the event channel, to store results of performance of the operations in the shared memory, and to perform control so that the results of the performance of the operations are sent to the guest OS unit via the event channel.
