移动平台Android操作系统虚拟化技术的实现
Implementation of OS-level virtualization technology for Android on mo-bile platform
摘要
Abstract
The virtualization technology research is gradually moving from the server area to the field of mobile intelli-gent devices. The existing virtualization architecture requires a large number of instruction translations between the physi-cal hardware layer and the virtual machine, which is of high cost and low efficiency. In order to solve this problem, it pro-poses a lightweight mobile operating system level virtualization architecture. It is based on the Linux kernel namespace mechanism to expand the driver namespace framework to achieve multiple virtual Android systems running simultaneously. In addition, the universal active-inactive model is designed to ensure the isolation and multiplexing of the hardware devices among virtual systems in order to solve the conflict produced when multiple virtual Android systems have access to a set of hardware devices simultaneously. Experimental results show that the virtual Android systems do not increase the over-head in the CPU utilization while the memory usage decreased by 6.7%, which proves that this virtualization architecture has a high versatility and practicality.关键词
