摘　　要：私有桌面云被广泛应用在集中计算、集中管理、远程办公等场景中。现有的私有桌面云多基于OpenStack云操作系统搭建,然而,该操作系统在使用时会出现虚拟机开启时间过长导致用户等待的问题,无法满足某些应用的高实时性要求。对此,使用模板镜像策略和网络连接存储策略作为云存储层解决方案,提出一种虚拟机可瞬时开启(ISVM)的私有桌面云架构。ISVM桌面云架构包括云管理层、云存储层、云服务层。经过测试和分析发现,ISVM私有桌面云架构的虚拟机开启时间约为OpenStack云平台虚拟机开启时间的1/100,达到了毫秒数量级,能够满足应用的实时性要求。Private desktop cloud is widely used in various kinds of application scenarios, such as centralized computing, centralized management, and remote office. Existing private clouds are mostly based on OpenStack operating system, however, OpenStack encounters a problem that it takes a long time to start a virtual machine when it is used in private desktop cloud, so it is unable to meet the real-time requirement in some application scenarios. In this paper, using template image strategy and network attached storage strategy for the cloud storage layer, Instant-Start Virtual Machine （ISVM） private desktop cloud architecture was proposed. ISVM private desktop cloud architecture consisted of cloud management layer, cloud storage layer, and cloud service layer. Through testing and analyzing, the time of starting virtual machines in ISVM architecture is about one percent of the time in OpenStack architecture, reaching millisecond order of magnitude and meeting the real-time requirement of some application scenarios.
