Virtual-machine cold migration method and apparatus, electronic device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory connected with the at least one processor communicatively;
• wherein the memory stores instructions executable by the at least one processor to cause the at least one processor to perform a virtual-machine cold migration method comprising:
• 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 a source physical machine where the virtual machine is located being different nodes;
• and
• migrating, by means of point-to-point data transmission, system disk data and data disk data in the virtual machine from the source physical machine to the target physical machine to obtain a migrated virtual machine, and deleting the virtual machine on the source physical machine.
