[ovirt-users] Re: VmMediatedDevices help for vGPU in overt 4.5

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()
