Abstract: A service container creation method and apparatus, where the method includes receiving, by a virtualization layer in a network functions virtualization (NFV) infrastructure (NFVI), a container creation message from a virtualized infrastructure manager (VIM) for a target service, creating, by the virtualization layer, a service container in the NFVI, deploying the target service in the service container, according to the container creation message, and establishing, by the virtualization layer according to a timer type in the container creation message, a binding relationship between the service container and one or more central processing units (CPUs) in the NFVI. Hence, isolate performance impact posed by a high-precision timer in an NFV system within a range of a single service container such that the NFV system considers performance of each service container while ensuring flexible service deployment.
