Abstract: This application provides a service process invoking method and a related apparatus. The method includes: An application process obtains a context of a binder process; the application process obtains a handle of a service process based on the context of the binder process; the application process runs a program of the binder process based on the context of the binder process, to obtain a context of the service process based on the handle of the service process; and the application process runs a program of the service process based on the context of the service process, to respond to a binder request of the application process, where the binder request is used to request a system service provided by the service process. In embodiments of this application, actual power consumption is accurately reflected.

Abstract: This application provides a method for migrating a virtual machine and an apparatus. The method is applied to a source-end physical host, the source-end physical host includes a host machine operating system and a source-end virtual machine running in the host machine operating system, and the host machine operating system includes a PF driver. According to the technical solutions of this application, memory consistency, before and after a migration process, of a virtual machine configured with a pass-through device can be ensured.
