Claim 8:
9. The data transmission method of claim 1,
wherein determining the second information comprises:
determining, by the daemon process, a host virtual address of the to-be-accelerated data in a virtual machine memory according to a virtual machine physical address of the to-be-accelerated data in the first information and a first preset mapping relationship between the virtual machine physical address and the host virtual address;
copying, by the daemon process, the to-be-accelerated data to a host memory buffer according to the host virtual address of the to-be-accelerated data in the virtual machine memory; and
determining, by the daemon process, a host physical address of the to-be-accelerated data in the host memory buffer according to a host virtual address of the to-be-accelerated data in the host memory buffer and a second preset mapping relationship between the host virtual address and the host physical address, and

wherein sending the second information to the hardware accelerator comprises sending, by the daemon process, the host physical address of the to-be-accelerated data to the hardware accelerator, and
wherein the data transmission method further comprises obtaining, by the hardware accelerator, the to-be-accelerated data from the host memory buffer according to the host physical address of the to-be-accelerated data.
