The invention discloses a fault monitoring method and a fault monitoring device for a virtual machine cluster. The method comprises the steps of receiving a notification command which indicates that a heart rate of the virtual machine cluster is abnormal via a host machine; judging whether a virtual machine at a local node is a DC node by the host machine according to prerecorded node information; when the virtual machine is the DC node, judging whether the virtual machine operates normally; when the virtual machine operates normally, using the virtual machine as the DC node by the host machine, and sending a message to the other host machine; when the virtual machine operates abnormally, acquiring the running state of the other hose machine virtual machine by the host machine, and judging whether the other host machine virtual machine operates normally; and when the other host machine virtual machine operates normally, using the other host machine virtual machine as the DC node. According to the method and the device provided by the invention, the state of the virtual machine cluster is monitored by the host machine, that is to say own resources of the host machine are used for performing fault monitoring on the cluster without the help of external tools, so that costs are reduced, and thus monitoring is autonomous and controllable due to no aid of external factors.
Description
technical field [0001] The invention relates to the field of virtual machines, in particular to a fault monitoring method and device for virtual machine clusters. Background technique [0002] For virtual machine clusters, when a controller node fails, the related resource services on the node will be switched to another node, and then the failed node needs to be restored, so cluster failure monitoring is particularly important. [0003] There may be a virtual machine in each controller that establishes a cluster, and these virtual machines need to establish a cluster and monitor the cluster. In the case of two control nodes, if the heartbeat of the virtual machine cluster is interrupted and the two nodes exist in isolation, the quorum will not work, which will cause the two nodes to compete for resources and fail to implement fault monitoring. [0004] For the virtual machine cluster of two control nodes, IP Quorum is mainly used to realize monitoring at present, that is, ...
