Abstract: A virtual machine migration method and apparatus, that the method includes: downloading an image file of a to-be-migrated virtual machine from an object storage; starting a preset command to process the downloaded image file, to obtain a private image corresponding to the image file of the to-be-migrated virtual machine, and provisioning, by using the private image, a virtual machine that runs on a destination virtualization platform, where the preset command is configured based on a difference between a source virtualization platform and the destination virtualization platform. According to the foregoing method, the image file of the to-be-migrated virtual machine is processed by executing the preset command, so that automatic migration of the image file of the to-be-migrated virtual machine can be implemented, and a user does not need to perform a manual operation. This effectively improves migration efficiency and meets a user requirement.

Abstract: An image file conversion method includes: obtaining an original image file of a virtual machine on an original platform; detecting whether the original image file has a first file characteristic and a second file characteristic that are corresponding to a target platform, wherein the first file characteristic comprises a target driver used when the virtual machine runs on the target platform, and the second file characteristic comprises a target file format supported by the target platform; and changing, in response to detecting that the original image file does not have at least one of the first file characteristic or the second file characteristic, the original image file by calling a predetermined interface, to obtain a target image file of the virtual machine on the target platform, wherein the target image file has the first file characteristic and the second file characteristic.
