在CloudStack平台与OpenStack平台共存的环境中，为了使CloudStack平台中已创建的KVM虚拟机在迁移到OpenStack平台后可以被OpenStack平台的控制节点正确识别并接管，提出了一种将CloudStack平台中已经存在的虚拟机动态迁移到 OpenStack 平台的方法。通过将传统基于本地存储的 KVM 虚拟机迁移方法与CloudStack以及OpenStack云计算平台自身特点相结合，重新对虚拟机迁移相关文件进行组合，实现了虚拟机跨平台的动态迁移。实验结果表明，本方法不但可以完成将KVM虚拟机成功从CloudStack平台迁移到OpenStack平台的任务，而且在时间上与传统方法相比并未产生其他时间成本。

To make KVM virtual machine which have been created in CloudStack platform identified and taken over correctly in CloudStack and OpenStack concomitant environment, propose a method for live migration of KVM virtual machine from CloudStack to OpenStack. By combining traditional KVM virtual machine migration method based on lo-cal storage and the characteristics of CloudStack and OpenStack cloud computing platform, regrouping virtual machine migration-related documents, we achieved the dynamic migration of virtual machines across platforms. The experimental results show that the method can not only successfully completed the KVM virtual machine migration task from Cloud-Stack to OpenStack, but also have no more other time cost than the traditional method.

随着教育信息化的不断深入,各高校都配备了多媒体教室。在实际的使用中,由于多媒体教室自身物理位置分散、使用人员复杂、管理人员缺失等实际问题,导致多媒体教室计算机在病毒防护、硬件管理、软件升级以及需求响应上出现不足。管理、维护好多媒体教室的计算机设备是保障教学活动正常进行的重要一环。在桌面虚拟化技术不断发展今天,通过开源Cloud Stack云平台管理软件来实现媒体教室的桌面虚拟化,能够大大减少多媒体教室的人力、资金的投入,同时也能够极大的为教学工作者提供便利。

With the development of educational informationization unceasingly thorough, various universities are equipped with multimedia classrooms. In actual use, due to its physical location distributed multimedia classroom, using complex personnel, man?agement personnel and lack of practical problems, leading to problems in the multimedia classroom computer virus protection, hardware management, software upgrade and demand response. Management and maintenance of computer equipment in multi?media classroom is to guarantee the normal teaching activities are an important part of the. In desktop virtualization technology development today, through the open source CloudStack cloud platform management software to realize the virtual desktop me?dia classroom, can greatly reduce the multimedia classroom of manpower, funds, but also can greatly facilitate the teachers.
