Abstract

The invention provides a virtual machine cold migration method and device, electronic equipment and a storage medium, and relates to the field of artificial intelligence such as cloud computing and distributed storage, and the method comprises the steps: selecting a node as a target physical machine from nodes of a cluster where a to-be-migrated virtual machine is located, the target physical machine and the source physical machine where the virtual machine is located are different nodes; respectively migrating the system disk data and the data disk data in the virtual machine from the source physical machine to the target physical machine through a point-to-point data transmission mode to obtain the migrated virtual machine, and recycling the virtual machine on the source physical machine. By means of the scheme, manpower and time cost can be saved, and storage resources can be saved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to a virtual machine cold migration method, device, electronic equipment, and storage medium in the fields of cloud computing and distributed storage. Background technique [0002] In cloud-native scenarios, virtual machines basically run as independent entities on physical machines as carriers. For some reason, such as physical machine disk failure, network failure, hacker attack, etc., the virtual machine running on the physical machine will be in an unsafe or unstable state. In order to solve this problem, it is usually necessary to perform cold migration on the virtual machine. [0003] The traditional cold migration method includes: determining the target physical machine, exporting the data to be migrated from the source physical machine, opening up the network between the target physical machine and the source physical machine, migrating the data...
