FIELD: information technology.
SUBSTANCE: in some versions, the system comprises a hardware machine which includes an input/output device; and a virtual machine monitor to interface the hardware machine and a plurality of virtual machines. In some versions, the virtual machine comprises a guest virtual machine to write input/output information related to an input/output operation and a service virtual machine comprising a device model and a device driver, wherein the device model invokes the device driver to control a part of the input/output device to implement the input/output operation using the input/output information, and wherein the device model, the device driver and the part of the input/output device are assigned to the guest virtual machine.
EFFECT: high efficiency of the input/output operation in a virtualisation environment.
