Live migration of virtual machines (VMs) is a key feature of server virtualization that underlies numerous operations in cloud computing platforms such as routine maintenance, load balancing, scaling to handle peak demands, and saving energy. Even though work in both industry and academia has made impressive advances in live migration technology, several important challenges remain to be addressed. This research investigates new VM migration mechanisms having better performance, robustness, and security. In particular, this work explores (1) simultaneous live migration of multiple VMs using distributed de-duplication and scatter-gather transfer of memory contents, (2) fault-tolerant VM migration to recover VMs after a failure during live migration, and (3) secure live VM migration techniques that reduce the performance impact of encryption and increase robustness against attacks.This research benefits modern data centers by advancing the state-of-the-art in live VM migration technology. Broader impacts include technology transfer, outreach to local high schools, and involving undergraduates, women and minority students in research. Integration of research with education includes development of course modules, course projects, and an advanced topics graduate course.

虚拟机（VM）的实时迁移是服务器虚拟化的一个关键特征，它是云计算平台中许多操作的基础，例如日常维护、负载平衡、扩展以处理峰值需求以及节省能源。尽管工业界和学术界的工作在实时迁移技术方面取得了令人印象深刻的进展，但仍有一些重要的挑战有待解决。本研究探讨新的虚拟机迁移机制具有更好的性能，鲁棒性和安全性。特别是，这项工作探索了（1）使用分布式重复数据删除和存储器内容的分散-聚集传输的多个VM的同时实时迁移，（2）容错VM迁移，以在实时迁移期间发生故障后恢复VM，以及（3）安全的实时虚拟机迁移技术，可降低加密对性能的影响，并提高抵御攻击的鲁棒性。这项研究通过推进最先进的虚拟机实时迁移技术。更广泛的影响包括技术转让、与当地高中的外联以及让本科生、妇女和少数民族学生参与研究。研究与教育的整合包括课程模块，课程项目和高级主题研究生课程的开发。
