FIELD: information technology.
SUBSTANCE: various embodiments of the present invention relate to dual-mode virtual device approaches. In certain versions, the dual-mode device is a virtual device which is based on real components of hardware. The versions provide a "high-efficiency mode" which is not present in the original hardware device. Software drivers and other software designed for interaction with the original hardware device and not designed to use the said high-efficiency mode continue to use "conventional mode" - virtualisation of hardware devices, while upgraded versions of guest software can identify and use the high-efficiency mode - idealised virtualisation.
EFFECT: high level of compatibility with software running in a guest environment similar to the hardware device virtualisation approach.
