Problems solved by technology

However, due to the failure of the virtual machine disk, the problem that the system or application program on the virtual machine of each VNF (Virtualized Network Function) instance after NFV cannot be used often occurs. Although there are various disaster recovery software or mechanisms, for the application It is still difficult to solve the problems caused by the data disk that the program does not access, such as hanging and being unable to operate. At present, there is no universal and reliable solution in the industry.

Abstract

The invention provides a detection and recovery method and device for a virtual machine fault. The method comprises the steps that a detection and recovery module acquires the state of a virtual machine from a detection agent module deployed in the cloud virtual machine; whether the virtual machine has a fault is judged; and when the virtual machine has a fault, the detection and recovery module initiates virtual machine reboot or virtual machine migration operation. Through the detection and recovery method and device, detection and automatic recovery of the virtual machine fault in a virtualization system in the prior art are realized, and therefore the effect of improving virtual machine reliability under a virtualization technology is achieved.

Description

technical field [0001] The present invention relates to the technical field of virtual machine fault handling in a virtualization (Network Function Virtualization, NFV) system, and in particular, to a virtual machine fault detection and recovery method and device. Background technique [0002] In the virtualized NFV system, the cloud management system provides the processing of virtual disks. Operators will create virtual disks according to business needs, such as mounting corresponding virtual disks in virtual machines created and managed by openstack and vmware cloud management systems. Operators clearly require virtual disks to ensure the high reliability of the five nines of telecom, which is an unavoidable prerequisite for the commercialization of virtualized clouds. However, due to the failure of the virtual machine disk, the problem that the system or application program on the virtual machine of each VNF (Virtualized Network Function) instance after NFV cannot be us...
