Abstract

The invention relates to a management method for preventing split-brain of a virtual machine, a main server, a cloud computing system and a computer-readable medium. The method includes the steps of: when the main server detects that the first virtual machine on the first server cannot work normally, in the first Create a second virtual machine on the second server, and enable the second virtual machine to obtain access rights to the storage volume corresponding to the first virtual machine; the primary server instructs the second server to read the storage volume in the storage volume status information, according to which it is determined whether to start the second virtual machine. This method can better prevent the virtual machine from split-brain and has high reliability.

Description

technical field [0001] The invention relates to the field of cloud computing, and in particular, to a management method for preventing split-brain of a virtual machine, a main server, a cloud computing system and a computer-readable medium. Background technique [0002] The High Availability (HA) technology of virtual machines can ensure that virtual machines can be automatically migrated to other nodes in the event of physical machine failure or network failure. This function is very valuable in the cloud environment, and more and more cloud All platforms provide virtual machine HA function. The cloud platform network is divided into 3 planes, such as figure 1 As shown, they are the management plane, the service plane, and the storage plane. The management plane is mainly used inside the cloud platform and is used for the management of virtual machines or physical machines. The business plane is mainly used by virtual machines to provide services. The storage plane is mai...
