摘　　要：系统虚拟化和模拟技术对当今计算机科学研究和相关产业有着重要的影响.整合虚拟和模拟环境,让运行在虚拟机中的操作系统获得更多重要的服务是一项具有挑战性和有意义的工作.由系统虚拟化提供的虚拟机动态迁移技术作进一步扩展后,可整合这两个计算环境.提出Roam,一个支持在虚拟和模拟环境之间进行虚拟机动态迁移的框架.开发的Roam原型系统实现了Linux虚拟机在Xen和纯Qemu环境之间的动态迁移.相关性能测试表明Roam是一个可行的虚拟机动态迁移方案,并且虚拟机的停机时间和整体迁移时间都在一个可接受的范围内.Today system virtualization and emulation technology have a significant impact on both computer science research and industry.Integrating virtualized and emulated environment to make the guest operating system in the virtual machine（VM） obtain various crucial services is a challenge and important work.Live migration of virtual machines,a practical and novel technique provided by the system virtualization,can be extended to integrate the two computing environments.This paper proposes Roam,a live migration framework which can relocate VMs between virtualized and emulated environment.The proposed approach supports live VM migration between Xen VMM and purely Qemu.Performance measurements show that Roam is a feasible schema which achieves acceptable VM downtime and total migration time.
