@jrjatin It seems that the Nvidia doc targets H100. @herozyg was attaching A10 to a CVM. Would this steps work on A10? A10 does not have confidential computing support.

Missed that! Maybe give it a try to see if it helps. Also just ensure to install nvidia drivers with -m=kernel-open

May I kindly inquire if this issue has been resolved? Just as mentioned by @wdsun1008, integrating CVM with a non-cc GPU could be advantageous, considering we possess alternative software-based methods for confidential computing.

Please refer sev-snp-gpu to enable Nvidia GPUs in SEV-SNP VMs.
