Abstract: This application provides a virtualized device, and an interrupt processing method running on the virtualized device. The method includes: performing, by a processor, the following operations in a guest mode: receiving, by the processor, an interrupt request from hardware; determining, by the processor, a processing entity of the received interrupt request based on a correspondence between the interrupt request and the processing entity; and when the processing entity of the received interrupt request includes the virtual processor currently running on the processor, determining, by the processor based on a correspondence between the interrupt request and an interrupt service routine, the interrupt service routine corresponding to the received interrupt request, and invoking the interrupt service routine to process the interrupt request.

Abstract: The present disclosure discloses a file access method of a virtualization instance, including performing union on some image subfiles in a host operating system (host OS) and mounting a united directory to a union directory, and when an application in a library operating system instance needs to access a file in the union directory, causing a central processing unit to generate an exit event such that a hypervisor captures and processes the exit event, and during processing, converts an access request that is from the instance into an access request based on a system call of the host OS, and performs access.

Abstract: A container monitoring method and apparatus, which are used for monitoring a plurality of monitored objects running on a physical machine. The type of plurality of monitored objects comprising at least one of a container, a process-in-container, or a thread-in-container. The physical machines comprising a primary monitor. The primary monitor receives monitoring information respectively reported by the multiple monitored objects. Monitoring information of monitored objects of a same type in the multiple monitored objects is reported by using a same channel. The primary monitor determines respective service statuses of the multiple monitored objects according to the monitoring information and unique identifiers. This can reduce resources consumed during monitoring in the prior art, and resolve a problem that a requirement for multidimensional monitoring on a container cannot be met due to high resource consumption.
