Abstract

The invention relates to a virtual machine anti-cerebral fissure management method, a main server, a cloud computing system and a computer readable medium. The method comprises: when a main server detects that a first virtual machine on a first server cannot work normally, creating a second virtual machine on a second server, and making the second virtual machine to obtain the access permission ofa storage volume corresponding to the first virtual machine; and the main server instructing the second server to read the state information in the storage volume, and determining whether to start the second virtual machine according to the state information. According to the method, the virtual machine cerebral fissure can be better prevented, and the reliability is high.

Description

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