A method and an apparatus for managing one or more physical network interface cards and a physical host are provided. One or more virtual network interface cards are created, where each of the virtual network interface cards has a standard network interface card feature and an operation interface; the one or more virtual network interface cards are separately associated with one or more function modules of the physical network interface cards; and the physical network interface cards are managed by managing the one or more virtual network interface cards. In this way, differences in underlying hardware are shielded for an upper layer, and convenient and efficient centralized management are provided, thereby further improving network resource utilization.
