Virtual machine failure detection and recovery method

Abstract

The invention relates to the fields of cloud computing and network technique and in particular relates to a virtual machine failure detection and recovery method. The method comprises the following steps: 1, deploying an NFS network file system environment, establishing a mount point on an NFS server, putting a mirror image on the mount point of the NFS server, mounting shared storage on all the nodes, and establishing a virtual machine for the mirror image; 2, starting a detection node timer, detecting whether the network and the power supply are positioned in a normal state, otherwise transmitting a failure recovery instruction to a scheduler; 3, selecting available nodes by virtue of the scheduler according to the preset cpu load strategy and other scheduling rules; 4, regenerating a virtual machine which is the same as the original machine according to a configuration file generated in the process of establishing the virtual machine; and 5, starting the established virtual machine. According to the method disclosed by the invention, the problem that the virtual machine cannot be continuously used after physical node downtime is solved, and the method can be used for virtual machine failure detection and recovery.

Description

technical field [0001] The invention relates to the field of cloud computing and network technology, in particular to a virtual machine fault detection and recovery method. Background technique [0002] With the increasing development of the cloud computing industry, information security has already become the focus of attention. The security of data and the stability of application business operation are becoming more and more important. If the physical machine fails and the virtual machine is not migrated in time, the following problems will occur: [0003] One is that the business on the virtual machine is interrupted, the outside world cannot continue to access, and the business cannot continue, resulting in increasing losses to users. [0004] The second is data loss. Without a fault recovery mechanism, the data on the virtual machine cannot be migrated. As a result, the data before the fault cannot continue to be used, and the business cannot continue normally. Manual...
