Method, device and system for handling equipment faults in a virtual machine system

Abstract

The invention provides a method, device and system for processing equipment failures in a virtual machine system, and relates to the technical field of information. The method comprises the following steps: obtaining failure factors of the virtual machine system; positioning a host server, a virtual machine and / or storage equipment with failures in the virtual machine system according to the failure factors; and carrying out switching processing on the host server, the virtual machine and / or the storage equipment with failures. According to the scheme, the defect of only recognizing the failure of the host server in the prior art is solved, the host server, the virtual machine and / or the storage equipment with failures in the virtual machine system can be positioned, and switching processing can be carried out, so that the failure restoration time is shortened and the failure positioning accuracy is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method, device and system for handling equipment faults in a virtual machine system. Background technique [0002] An existing server virtualization system generally includes a virtualization management system, a host server, a storage device, and a virtual machine. A virtual machine consists of a series of virtual disk files, configuration files, etc. These files are stored in various storage devices, and the computing and communication resources used by the virtual machine are provided by the host server. During the operation of the virtualization system, when the host server fails, the virtualization management system will schedule the virtual machines running on the failed host to other normal running hosts to restart, so as to restore the application provision ability of the virtual machines and improve the availability of the virtualization system .

AI Technical Summary

Problems solved by technology

[0006] 2) The disk array card of the host server fails;

[0007] 3) Memory overflow failure of the host server operating system;

[0008] 4) Faults such as memory overflow of the virtual machine operating system;

[0009] 5) Storage device failure

[0010] Because the first three host server-level failures will cause the host operating system to be in a "fake death" state, that is, the data in the memory cannot be released and written to disk, but there is no problem with network detection. At this time, the host server cannot provide normal virtualization system services , the virtual machine hosted by the host server cannot run normally; and the fourth and fifth cases are not caused by the host failure. At this time, the virtual machine cannot run normally but there is no problem with the network detection of the host server.

[0011] Therefore, the above five types of faults will not cause the host server network detection to be interrupted, but will cause the associated virtual machines to fail to provide application capabilities. Rebooting on the host server, as a whole affects the overall availability level of the virtualization
