Configure the Nvidia VGPU profile on L40s

I’m using a Nvidia L40S on a server, which is running on Ubuntu Server 24.04 and i am trying to use virtualization on the ubuntu server by configuring the opnestack with the hypervisor of KVM/Qemu. But i couldn’t be able to achieve the Nvidia VGPU Slicing. The GPU Profiles are not being populated. Can someone please help us here.
