摘　　要：针对Openstack的高可用性问题,目前大部分的研究都集中在控制节点的高可用上,对于虚拟机的高可用研究较少。已有的虚拟机高可用方案存在无法适应多种故障场景、无法针对单个虚拟机粒度进行故障处理等问题。本文提出了一种基于Openstack的虚拟机高可用方案,方案使用控制组件和代理服务组件,配合不同故障的检测逻辑,实现多种故障场景下的虚拟机高可用。同时方案还引入了自治组概念,解决了代理服务组件故障或管理网故障场景下,代理服务组件无法继续进行故障检测和上报的问题。For the high availability of Openstack,most of the current research is focused on the high availability of control nodes,and there is little research on high availability of virtual machines.There are some problems in the existing high availability solutions of virtual machine,for example,these schemes unable to adapt to a variety of failure scenarios,and unable to deal with failure of virtual machine granularity.In this paper,a high availability scheme of virtual machine based on Openstack is proposed.The scheme uses control component and agent component,designs different fault detection logic,and realizes high availability of virtual machine in various fault scenarios.At the same time,the concept of autonomous group is introduced to solve the problem that the agent component can not detect and report faults in the scenario of agent component failure or management network failure.
