A method and apparatus for configuring an operating system

Abstract

A method and apparatus for configuring an operating system are provided in one or more embodiment of that present specification. The method includes determining a first physical memory segment available for a host operating system according to memory allocation information in preset system resource configuration information; Configuring a corresponding second physical memory segment for the guestoperating system according to the memory allocation information; Controlling the host operating system to initialize the first device resource according to the device allocation information in the system resource configuration information; According to the device allocation information, the guest operating system is controlled to initialize respective second device resources. By reserving a portion of the physical memory segments in the computer's physical memory, The guest operating system is configured with independent physical memory space, so that the guest operating system can run truly in the physical environment, thus ensuring the independent real-time operation of the guest operating system, thus ensuring the real-time performance of the guest operating system and effectively reducing the investment cost.

Description

technical field [0001] One or more of the descriptions relate to the field of computers, and in particular to a method and device for configuring an operating system. Background technique [0002] At present, with the accelerated integration of the new generation of information technology and traditional industries, and with the rapid development of industrial Internet technology, industrial production is being promoted in the direction of digitization, networking, and intelligence, and the use of advanced artificial intelligence and cloud computing And other Internet technologies to process industrial big data, thereby enhancing the industrial value of the industrial field. [0003] Currently, in order to improve data processing efficiency, a host operating system and at least one guest operating system are installed on the computer at the same time.

Problems solved by technology

[0003] Currently, in order to improve data processing efficiency, a host operating system and at least one guest operating system are installed on the computer at the same time. Specifically, an open source virtualization solution is used to virtualize the guest operating system in the industrial Internet computer, for example , KVM technology (Kernel-based Virtual Machine, kernel-based virtual machine technology), in which, because the computing module of KVM is implemented based on the thread model of Linux, it needs to be scheduled when responding to the client's access and control requests, and there is no guarantee for user requests Therefore, in many high-precision scenarios, it cannot support the real-time requirements of the business; in order to solve the problem of non-real-time response to requests, computer hardware is usually improved to ensure real-time performance, for example, using intel chips technology to ensure the real-time performance of the operating system, which will greatly increase the investment cost, and is not suitable for industrial Internet application scenarios that have high real-time requirements and strict cost control
