Abstract: Embodiments of the present disclosure disclose a computing device, and are applied to the field of computing devices. In the present disclosure, a virtual interrupt obtained by a host machine is mapped to a physical interrupt of a physical layer, and a virtual interrupt identifier corresponding to the physical interrupt is transferred to a virtual processor by using the physical layer. When a hardware layer transparently transmits the virtual interrupt identifier to the virtual processor, the virtual processor does not need to exit. This decreases a delay caused by exit of the virtual processor when software implements virtual interrupt routing.
