针对虚拟机在网络应用中部署开销高、存储规模大的问题，通过分析引导系统文件，将传统的虚拟机镜像分割为系统镜像和用户自定义镜像；虚拟化系统在启动的时候，同时读取2个镜像文件，随后采用unionfs进行镜像的融合，最终向用户提供完整的虚拟机操作系统。使用IOZONE软件对原型镜像虚拟机进行性能测试，结果证明：该方法可以显著减少虚拟机镜像的传输时间和系统的存储规模。

Aiming at the large virtual machine image problem, this paper proposes a process that splits a traditional image into a system image and a user-defined image by analyzing the booting system files.When a virtual system startup, it reads files from both images, then merges them by unionfs, finally provides a complete virtual operating system.The performance experiments using IOZONE show that the image method eliminates the system image redundancy, and greatly reduces the image storage.
