GPU virtualization Openstack A100

Hello,
I have the following issue:
I have one server DELL with A100 Nvidia. On the server Dell I can observe that nvidia-smi is working. Everything fine till now.
When I create an ubuntu virtual machine on this server Dell and I run: lshw -C display:
I get the following output:

**-display:0 UNCLAIMED *

After this I installed the Nvidia-driver and I run nvidia-smi. Now on the virtual machine, I have the following output: “No devices were found”.
If you have any ideea, let me know.
Thanks
