Operating system performance interference preventing apparatus of hypervisor system

Abstract

The present invention relates to an operating system performance interference preventing apparatus of a hypervisor system. The present invention includes a hardware physical layer, an operating system layer composed of a plurality of operating systems of different types, and a hypervisor that allocates basic resources for using system resources of the hardware physical layer for each of a plurality of operating system domains corresponding to a plurality of operating systems constituting the operating system layer so that the plurality of operating systems operate in a virtual machine environment, and the basic resources allocated by the hypervisor for each of the plurality of operating system domains include a first resource consumed when a specific operating system domain, which is one of the plurality of operating system domains, directly uses the system resources, a second resource consumed when the hypervisor uses the system resources, and a third resource consumed in a process of using the system resources by a device driver domain that drives an input/output device of the hardware physical layer when the specific operating system domain uses the input/output device. According to the present invention, there is an effect of solving the problem that a phenomenon, in which system resources allocated according to the original specifications for each operating system on the hypervisor become insufficient, occurs due to an occurrence of a situation, in which some operating system domains operating on the hypervisor excessively use system resources, and remaining operating system domains, particularly a real-time operating system, cannot operate while satisfying real-time requirements.
