A list of the vGPU types enabled in the compute node.

Some pGPUs (e.g. NVIDIA GRID K1) support different vGPU types. User can use
this option to specify a list of enabled vGPU types that may be assigned to a
guest instance. But please note that Nova only supports a single type in the
Queens release. If more than one vGPU type is specified (as a comma-separated
list), only the first one will be used. An example is as the following:
    [devices]
    enabled_vgpu_types = GRID K100,Intel GVT-g,MxGPU.2,nvidia-11
""")

    conf.register_group(devices_group)
    conf.register_opts(vgpu_opts, group=devices_group)
