【摘要】：虚拟机动态迁移技术是现今虚拟化技术的核心组成部分,给数据中心的管理与维护带来巨大的便利.针对局域网虚拟机动态迁移的预拷贝策略于2005年被提出,并因为其毫秒级的停机时间以及对应用较小的影响,被各大虚拟化平台广泛采用.与此同时,关注总体迁移时间的延迟拷贝策略也逐渐被业界接受.随着云计算的进一步发展,广域网虚拟机动态迁移的需求被提出,成为了目前学术界的研究热点.动态迁移中,最为复杂的部分为内存状态的迁移,保证数据的一致性是所有迁移策略的必要前提.综述了近几年来,虚拟机动态迁移领域中内存迁移技术的研究与发展,并指出目前研究中存在的问题以及今后的发展.
[Abstract]:Virtual machine dynamic migration technology is the core component of today's virtualization technology, which brings great convenience to the management and maintenance of the data center. The pre-copy strategy for dynamic migration of local area network virtual machines was proposed in 2005, and is widely used by the major virtualization platforms because of its millisecond downtime and less impact on applications. At the same time, the delayed copy strategy that focuses on the overall migration time is also gradually accepted by the industry. With the further development of the cloud computing, the demand of the dynamic migration of the virtual machine of the wide area network has been put forward, and has become the research focus of the academic circles at present. In the dynamic migration, the most complex part is the migration of the memory state, and the consistency of the data is the necessary prerequisite for all the migration strategies. This paper reviews the research and development of memory migration in the field of dynamic migration of virtual machines in recent years, and points out the problems existing in the current research and the future development.
