Specifically, the physical resources in this embodiment may include a GPU (graphics processing unit), and the corresponding virtual resources are vGPU resources, that is, GPU resources are virtualized to generate vGPU resources.
Furthermore, the type of the virtual resource may be configured on the nova-computer service of the host where the virtual resource is located, and information such as a manufacturer may also be configured, which is not specifically limited herein. The virtual resources which are not configured cannot be reported to the resource management system and cannot be used by the cloud platform.
For example, the configuration items are as follows:
[gpu_devices]
vgpu_types＝nvidia-181,nvidia-182
[vgpu_nvidia-181]
gpu_addresses＝0000:af:00.0,0000:86:00.0
[vgpu_nvidia-182]
gpu_addresses＝0000:3b:00.0
a general server supporting the GPU can be equipped with 4 GPU cards, and the vppu _ devices records the virtualized vGPU _ types of the GPU. The address (GPU addresses) of the server where the physical GPU corresponding to the nvgpu of the nvia-181 type is located is recorded in [ vGPU _ nvidia-181], 0000: af:00.0 and 0000:86:00.0 indicate that two GPU cards use the vGPU of the nvia-181 type. Similarly, [ vGPU _ nvidia-182] records the address of the server where the physical GPU corresponding to the nvia-182 type of vGPU is located, and 0000:3b:00.0 shows that one GPU uses the nvia-182 type of vGPU.
Further, the nova-computer service is restarted, and the configured virtual resources are automatically sent and reported to the resource management system. The reported data is shown in table 1, for example:
TABLE 1
Wherein, the two GPUs 0000: af:00.0 and 0000:86:00.0 support 16 (max _ unit) vGPUs, and the GPU 0000:3b:00.0 supports 8 vGPUs.

Furthermore, after the virtual machine is successfully created, the virtual resources bound by the virtual machine can be checked. As a possible implementation manner, it may be checked whether the configuration file of the virtual machine is bound with hostdev tags, where each hostdev tag corresponds to a virtual resource. As another possible implementation, the virtual machine may be entered and the virtual machine bound virtual resources viewed via the lspci command.
