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: An ion implantation system is provided having an ion source configured to form an ion beam from aluminum iodide. A beamline assembly selectively transports the ion beam to an end station configured to accept the ion beam for implantation of aluminum ions into a workpiece. The ion source has a solid-state material source having aluminum iodide in a solid form. A solid source vaporizer vaporizes the aluminum iodide, defining gaseous aluminum iodide. An arc chamber forms a plasma from the gaseous aluminum iodide, where arc current from a power supply is configured to dissociate aluminum ions from the aluminum iodide. One or more extraction electrodes extract the ion beam from the arc chamber. A water vapor source further introduces water to react residual aluminum iodide to form hydroiodic acid, where the residual aluminum iodide and hydroiodic acid is evacuated from the system.

Abstract: In the website system of the application, when a client accesses a page of a website, a web server obtains an initial URL of a content file included in the to-be-accessed page and a version parameter of a current version of the website, generates a current URL of the content file, and adds the version parameter to a search part of the current URL of the content file, so that the client can obtain the content file from the web server according to the current URL. During version upgrade of the website, a developer does not need to change a path to a content file, does not need to manually change a URL of the content file, and does not need to update a name of the content file either. This improves website upgrading efficiency.
