A method and device for loading virtual machine snapshot data, the method comprising: in response to receiving startup instructions of multiple virtual machines, selecting target image files corresponding to multiple virtual machines from multiple image files stored in an image center, and caching multiple snapshot data in the target image files in the form of stripe data to multiple snapshot cache nodes in an elastic block storage EBS cluster according to a preset first stripe size; wherein the EBS cluster is configured with a snapshot distributed cache formed by multiple snapshot cache nodes to be responsible for caching and distributing snapshot data; creating a data loading cloud disk corresponding to each virtual machine, and for each virtual machine, loading the snapshot data required to start the virtual machine from the snapshot storage space of multiple snapshot cache nodes through the data loading cloud disk corresponding to the virtual machine.
