云计算实验平台虚拟机镜像的管理与维护

摘要

针对云平台在实验教学应用中出现的一些问题,设计实现了虚拟机镜像管理与维护系统.通过在云平台的持续集成环境中部署脚本,实现对镜像的缓存、回收、更新升级等维护功能,给出了维护模块的具体实现方法和维护管理流程.镜像的管理和维护有利于虚拟机保持良好运行,使云平台可以快速创建实验环境和及时回收实验资源,为实验教学提供有效的环境支撑.%In view of some problems in the application of the cloud platform in experimental teaching , a management and maintenance system for the virtual machine mirror image is designed and realized .Through the deployment of scripts in continuous integration environment of the cloud platform , the maintenance functions such as mirror image caching , recycling , updating , upgrading , etc ., can be realized . The management and maintenance of the mirror image are beneficial for the virtual machine to maintain good operation , so that the cloud platform can quickly create the experimental environment and recycle the experimental resources in time to provide effective environmental support for the experimental teaching .
