Method and a system for building a virtual mechanism based on a processor

Abstract

The invention provides a method and a system for building a virtual mechanism based on a processor. In a user space virtual machine management program, a configuration command is input to create and start a virtual machine. The user interface receives and parses configuration commands and accesses the kernel module interface. Creating device files in the physical machine file system as kernel module interfaces for user space hypervisor to access the physical machine kernel; The virtual management of the physical machine kernel responds to the user space hypervisor access, initializes the datastructure of the virtual machine instance, fills the virtual CPU state data, saves the current CPU running state of the physical machine, and accesses the HMCode specific call to switch to the virtualmachine running state. Lightweight virtual machine based on domestic Shenwei processor platform is built to realize virtual machine creation, start, pause, stop and other key input and output devicevirtualization functions, including virtualized storage access, virtualized display device and virtual network card.

Description

technical field [0001] The present invention relates to the field of virtual machine construction, in particular to a processor-based virtual machine construction method and system, in particular to a domestic Shenwei processor-based virtual machine construction method and system. Background technique [0002] At present, the domestic Shenwei processor architecture is constantly maturing, and it is gradually being widely used in many different application fields, especially in the key application scenarios of Chinese government agencies and related organizations. Considering that the domestic Shenwei processor platform is independently developed, maintained and controlled by Chinese research institutes, this platform will obviously have excellent security and credibility, and at the same time, it can be adjusted and developed according to the special needs of Chinese organizations. Adaptation also increases the flexibility and breadth of its application. Therefore, the comp...

Problems solved by technology

[0005] At present, the design and implementation of a lightweight virtual machine construction method based on the domestic Shenwei processor needs to face the following problems: First, unlike the mainstream x86 instruction set platform, the Shenwei processor platform does not provide hardware-native virtualization support acceleration Therefore, it is impossible to realize efficient virtual machine operation management by calling the hardware interface, but must realize virtualization through software processing

In addition, the existing open source virtualization implementation solutions cannot be directly transplanted and run on the instruction set of the Shenwei processor platform, and native solutions must be developed based on this
