桌面云镜像管理模块研究——以高校开放式桌面云实训室为例

Research on Image Management Module for Desktop——Case Study of the Open Desktop Cloud Training Room in Colleges

相较于传统实训室的"专室专用",高校开放式桌面云实训室采用了对虚拟镜像的版本管理和增量存储的方法,抑制虚拟镜像的无序蔓延,从而达到节省虚拟镜像的存储空间和传输时间的目的。实验结果表明,在使用了版本控制增量存储后,镜像占用的存储空间和镜像上传时间大幅减少,提升了镜像管理效率。

Compared with the traditional training room,"special room for special use",in the open desktop cloud training room,the method of version management and incremental storage of the virtual images is proposed.It inhibits the spread of virtual images,thus saving the storage space and transmission time of virtual images.The experimental results show that,after using version control incremental storage,the storage space occupied by images and the upload time of images is greatly reduced,which improves the efficiency of image management.
