PURPOSE: A multi frame buffer emulation system in a virtual machine and a method thereof are provided to improve the performance of a VM(Virtual Machine) by using an operating function of a host machine and reducing the operation of the VM. CONSTITUTION: A display buffer(201) displays multi frame buffers synthesized with frame buffers(101-103). A display controller register(104) stores frame buffer information and display state information. A VM records the frame buffer information and the display state information in the display controller register. A host machine periodically synthesizes the frame buffers based on the frame buffer information and the display state information recorded in the display controller register and updates the display buffer to render the multi frame buffers.
