Confidential VM with H100 GPU blocked — "experiment flag not enabled" for project

Google Cloud Compute Infrastructure

Hi,

I’m trying to create a Confidential VM instance with GPU on Google Cloud, but I’m getting an error saying the confidential GPU support experiment flag is not enabled for my project.

Machine type: A3 (a3-highgpu-1g)
GPU: NVIDIA H100
Zone: us-central1

I’ve verified:

  • GPU quota is in place
  • Using a supported machine type and GPU combo
  • Confidential VM API is enabled

It seems my project needs to be allow-listed for this preview feature. How do I get the experiment flag enabled? Is there a sign-up form or internal process to request this?

Any help appreciated. Thanks!
