Claim 3:
4. The data transmission method of claim 3, wherein the hardware accelerator supports a plurality of virtual functions (VFs), and wherein the data transmission method further comprises:
querying, by the daemon process after determining the host physical address of the to-be-accelerated data, from a preset binding relationship between a virtual accelerator and a VF, a target VF bound to the target virtual accelerator;
further sending the host physical address by sending, by the daemon process, the host physical address of the to-be-accelerated data to the target VF;
obtaining, by target VF and according to the host physical address of the to-be-accelerated data, the to-be-accelerated data from the virtual machine memory corresponding to the virtual machine physical address of the to-be-accelerated data; and
performing, by the target VF, the acceleration operation on the to-be-accelerated data.
