An accelerator virtualization method is disclosed. The method includes: selecting, by a centralized resource manager, a matched physical accelerator from a physical accelerator resource pool as a matching physical accelerator according to to-be-created virtual accelerator information in a virtual machine resource configuration command; sending, by the centralized resource manager, a first virtual machine creation command to a virtual machine monitor, so that the virtual machine monitor can create a first virtual machine including a first virtual accelerator corresponding to the matching physical accelerator; or sending, by the centralized resource manager, a second virtual machine creation command, which includes a description information obtaining identifier, to a virtual machine monitor, so that the virtual machine monitor can create a second virtual machine after receiving the second virtual machine creation command, and the second virtual machine generates a second virtual accelerator after obtaining description information according to the description information obtaining identifier.
