| 摘 要： | 虚拟化技术的研究正逐渐从高性能服务器端转向移动智能设备领域. 现有的虚拟化方案多是采用多内核方案，系统负载高，效率低. 针对车载系统等平台多屏显示以及资源受限等问题，本文提出一种基于容器技术的Android轻量级虚拟化方案. 该方案通过利用Namespace资源隔离机制和Cgroup资源分配机制，使得ARM平台在资源使用较少的同时，能够同时启动多个Android虚拟机，并且各虚拟机上的屏幕显示相互独立. 测试结果表明，该方案的内存占用率较双系统方案降低了7%，而平均CPU使用率较原生Android系统仅增加了1%.

| Abstract: | The virtualization technology research is gradually moving from high-performance server to mobile intelligent devices. Existing virtualization solutions are mostly multi-core solution with high system overhead and low efficiency. This paper presents a lightweight virtualization scheme based on Linux container for multi-screen display and resource limitation of vehicle system. Our program, through the use of Namespace resource isolation mechanism and Cgroup resource control mechanism, can start several Android virtual machines on the ARM platform at the same time, while displaying on different screens and running independently. The performance test results show that on the ARM platform, the program uses less than 7% of the memory of the two systems, and the average CPU usage after virtualization is only 1% higher than the native Android system. |
