说明书
发明名称:集群服务器的虚拟机迁移方法、 装置、 服务器及存储介 质
技术领域
[0001] 本发明属于计算机技术领域, 尤其涉及一种集群服务器的虚拟机迁移方法、 装 置、 服务器及存储介质。
背景技术
[0002] 随着计算机互联网的飞速发展, 各种服务提供商层出不穷, 他们提供的服务也 是五花八门, 例如下载、 视频、 音乐等, 极大地增加了网络用户的数量, 同吋 由于可供选择的服务的增多, 网络用户在选择服务吋对服务质量的要求也提高 了。 因此, 对于服务提供商来说服务质量 (Quality of Service, 简称 QoS) 至关 重要。 由于方便管理、 节约成本等原因, 服务商都搭建集群服务器以搭载服务 , 因此, 服务提供商对外提供的服务实际都搭载在 KVM (Kernel-based Virtual Machine) 虚拟服务器上, 但是一些虚拟机服务器的位置选择未经过优化, 导致 用户访问服务吋会感到明显的网络延迟, 而且即使当吋选择较为优秀的服务位 置, 当用户数量、 用户分布区域等发生变化吋, 也需要对虚拟机服务器的位置 进行调整, 以方便用户进行访问, 提高用户服务的 QoS。
[0003] 目前针对这种情况一般的解决办法是人工分析, 手动迁移 KVM虚拟服务器到 位置更利于服务用户的地点。 现有技术中虚拟机在对外服务的情况下难以收集 所有访问服务用户的访问地址, 即使收集到大部分用户访问信息还需要进行人 工分析和运维人员对虚拟机进行人为的迁移, 缺乏实吋性, 并且 KVM虚拟机迁 移过程也难以把控。 很难做到实吋的提高用户服务的 QoS。
[0004] 目前虚拟机迁移有很多通用的工具, 如 Virsh命令行等, 但是这些工具都需要手 动指定目标的迁移, 难以自动的完成 KVM虚拟机迁移的过程, 也对这一优化过 程有一定影响。 因此现有技术难以实现虚拟机的实吋自动迁移, 以达到提高用 户服务的 QoS的目的。
技术问题 [0005] 本发明的目的在于提供一种集群服务器的虚拟机迁移方法、 装置、 服务器及存 储介质, 旨在解决由于现有集群服务器中虚拟机的迁移效率低下, 导致集群服 务器的服务质量较低的问题。
