Abstract: A method and an apparatus for migrating a virtual machine across virtualization systems, and a system, where a first virtualization system in which a source virtual machine is located specifies a temporary address of a destination virtual machine. After a second migration tool of a second virtualization system migrates the to-be-migrated virtual machine to the second virtualization system to generate the destination virtual machine, a first migration tool of the first virtualization system controls a migration agent on the destination virtual machine to modify the address of the destination virtual machine to an address of the source virtual machine such that the address of the virtual machine remains unchanged before and after migration, thereby shortening service interruption duration caused by virtual machine migration.

Abstract: A macro image shooting method uses at least two macro cameras having different focal lengths. When a zoom ratio is within a first ratio range, an image captured by a first macro camera is displayed in a viewfinder frame. When the zoom ratio is a camera switching ratio, the image displayed in the viewfinder frame is switched from the image captured by the first macro camera to an image captured by a second macro camera. When the zoom ratio is greater than the camera switching ratio and is within a second ratio range, the image captured by the second macro camera is displayed in the viewfinder frame.
