Abstract: The disclosure provides a method for managing multiple operating systems in a terminal. The terminal includes multiple operating systems and a management system. The management system is configured to manage the multiple operating systems. The management system includes a cross-system application database. The method includes: when a first operating system in the multiple operating systems runs in a foreground, and a second operating system in the multiple operating systems runs in a background, if the second operating system receives a first message of a first application in the second operating system, sending, by the second operating system, a notification message to the management system; storing, by the management system, the notification message into the cross-system application database; and listening, by the first operating system, on the cross-system application database, and outputting a prompt of the first message when listening and obtaining the notification message.

Abstract: Embodiments of this application disclose an iOAM packet transmission method and related apparatus. In the method, a tail node device in a measurement domain receives a first iOAM packet, and determines whether the first iOAM packet includes an important data identifier. If the first iOAM packet includes the important data identifier, the tail node device generates, based on the first iOAM packet, a notification message that includes first node information, and sends the notification message to a management device in an iOAM network. According to the solution in the embodiments of this application, only when the received first iOAM packet includes the important data identifier, the tail node device generates the notification message based on the first iOAM packet and reports the notification message.

Abstract: An operating system hot-switching method, applied to a mobile terminal running multiple operating systems, where the multiple operating systems include one foreground operating system and at least one background operating system, a current foreground operating system is a first operating system. The method includes obtaining an operating system switching instruction, where the operating system switching instruction includes an identifier of the second operating system and a switching identifier, releasing, according to the switching identifier, a hardware resource occupied by the first operating system, and switching the foreground operating system from the first operating system to the second operating system. Hence, the operating system hot-switching method ensures, to some extent, mutually exclusive access to and coordinated use of a hardware resource by multiple operating systems, thereby ensuring use reliability of the hardware resource after switching of an operating system.

Abstract: A display method, an apparatus, and a storage medium are provided. The method includes: rendering, by a first container, a to-be-displayed page to generate to-be-displayed image data, and encrypting the image data; and writing, by the first container, encrypted image data into a buffer corresponding to the first container, and sending instruction information to a second container of a terminal, where the instruction information is used to instruct the second container to securely display the encrypted image data. Because the containers are isolated from each other, the malware in the first container cannot access the image data displayed in the second container, and the second container securely displays the encrypted image data. In this way, security of displaying the image data can be improved while ensuring that an image display function is not restricted.
