Some pGPUs (e.g. NVIDIA GRID K1) support different vGPU types. User can use `enabled_vgpu_types` to specify the enabled vGPU types that a guest could consume from the host. NOTE(sbauza) : Since that configuration is shared between all virt drivers, we need to provide a single change that will just add that conf opt and then use it in separate series as a common base. That implies that configuration option is useless until we merge the code that reads it, but that's a necessary compromise for making sure we can move both Xen and libvirt efforts in parallel. Partially Implements: blueprint add-support-for-vgpu Co-Authored-By: Sylvain Bauza <sbauza@redhat.com> Change-Id: I56f9597e968eac041832cdb90fe52cf0d3b4a4ef

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. 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)
|
|
|
|
|
|
def list_opts():
|
|
return {devices_group: vgpu_opts}
