随着虚拟化技术逐渐在数据中心环境中的普及,虚拟化系统的容灾成效日益成为人们关注的焦点,而虚拟化集群的心跳算法是关系虚拟化容灾成效的关键技术之一.研究了一种虚拟化的心跳算法,该算法通过利用所有网络节点有序的进行网络心跳检测,输出一个布尔值,负责裁判进程的Master主机根据该值判断节点是否出现故障,可用于快速检测出集群环境中节点的故障.%As the gradual popularization of virtualization technology in data centre environment,disaster tolerance effect of the virtualization system has become the focus concerned by people increasingly,and the heartbeat algorithm of virtualization cluster is one of the key technologies to influence the disaster tolerance effect of virtualization. A heartbeat algorithm of virtualiza-tion is studied in this paper. The algorithm detects network heartbeats in order by using all network nodes,and then outputs a Boolean value. According to this value,the fault of the node is judged by the Master host which is in charge of progress judg-ment. It can be used to detect the fault of node in cluster environment rapidly.
