I am looking for an example on how to use the new VmMediatedDevices service to add an Nvidia vGPU in ovirt to guest vms. I had it working just fine in oVirt 4.4 when using the custom_properties method. Just need to understand the new method/way of doing it correctly using the python3-ovirt-engine-sdk.

You can retrieve the vGPU properties like:

service = connection.system_service().vms_service().vm_service('123').mediated_devices_service() vgpu_devices = service.list() first_vgpu = vgpu_devices[0] # id of the device first_vgpu.id # properties of the device [(p.name, p.value) for p in first_vgpu]

Example of adding and removing a vGPU device:

service = connection.system_service().vms_service().vm_service('123').mediated_devices_service() spec_params = [ovirtsdk4.types.Property(name=name, value=value) for name, value in (('mdevType', 'nvidia-22'), ('nodisplay', 'true'), ('driverParams', 'enable_uvm=1'))] service.add(ovirtsdk4.types.VmMediatedDevice(spec_params=spec_params)) service.device_service('456').remove()

HTH, Milan
