Abstract

The invention provides a virtual machine high availability implementation method and device and a storage medium. According to the virtual machine high-availability implementation scheme provided by the invention, when the server bearing the virtual machine accesses the shared storage abnormally, the virtual machine I / O request can be quickly switched to the management network link through the I / O agent to be normally issued, so that the non-shutdown service of the virtual machine can be quickly recovered, and the high-availability performance is improved.

Description

technical field [0001] The present disclosure relates to the technical field of cloud computing and network communication, and in particular to a method, device and storage medium for realizing high availability of a virtual machine. Background technique [0002] Virtual machine high availability (High Availability, HA) refers to the ability of the system to provide uninterrupted services, that is, to reduce the time for the system to stop services as much as possible. [0003] figure 1 It is a schematic diagram of the realization of high availability of virtual machines in the virtualized cloud platform architecture based on shared storage. In the existing technical solutions for high availability of virtual machines HA, it is assumed that server A and server B form a cluster, and the virtual machine vm1 on server A The storage image file is stored on the shared storage. When the storage network connection between server A and the shared storage is abnormal, the HA module ...
