A Lightweight Virtualization Solution for Android Devices

摘要

Mobile virtualization has emerged fairly recently and is considered a valuable way to mitigate security risks on Android devices. However, major challenges in mobile virtualization include runtime, hardware, resource overhead, and compatibility. In this paper, we propose a lightweight Android virtualization solution named , which is based on container technology. utilizes resource isolation based on namespaces feature and resource control based on cgroups feature. By leveraging them, can host multiple independent Android virtual machines on a single kernel to support mutilple Android containers. Furthermore, our implementation presents both a system service sharing mechanism to reduce memory utilization and a filesystem sharing mechanism to reduce storage usage. The evaluation results on Google Nexus 5 demonstrate that is feasible in terms of runtime, hardware resource overhead, and compatibility. Therefore, we find that has a higher performance than other virtualization solutions.
