Device virtualization system and method based on linux container

Abstract

The invention provides a device virtualization system and method based on Linux containers. Virtual device clients and a virtual device server are loaded between Android system HALs and a device subsystem; device operation requests are sent to the virtual device server through the virtual device clients; and then the virtual device server finishes function call in a manufacturer dynamic library, thus realizing agency for the device operations, or constructs device operation results, thus realizing reuse of the device subsystem. According to the device virtualization system and method provided by the invention, through loading the virtual device clients and the virtual device server in multiple Android systems and container management service in a Linux kernel, the agency for the device operations and the reuse of the device subsystem are finished, thus realizing virtualization of the device; a new method different from a traditional device virtualization method is provided; and the reuse of special devices (especially devices without open source code) such as Radios is realized in the multi-Android platform based on a Linux container technique.

Description

Technical field [0001] The present invention belongs to the field of communication technology, relates to equipment virtualization technology, and in particular relates to a Linux container-based equipment virtualization system and method. Background technique [0002] Virtualization technology is a technology that separates and decouples the underlying hardware devices from the upper operating system and application programs. Virtualization technology, as one of the important underlying support technologies of the current popular cloud computing platform, can greatly improve the resource utilization efficiency of physical equipment. Especially with the increasing diversification of smart communication devices and the continuous improvement of the performance of communication devices, the hardware resources of communication devices (such as smart phones) are currently in a relatively surplus state. Using virtualization technology to virtualize multiple operating systems can isol...

AI Technical Summary

Problems solved by technology

For some proprietary devices (such as telephone devices on the mobile phone platform, etc.), device manufacturers need to protect their intellectual property rights, which are usually source codes that are not developed; is very difficult

In addition, due to the diversity of device manufacturers and devices, there may be great differences even among similar device drivers, which also increases the difficulty of realizing device virtualization.
