Azure ML Studio - Attached Compute Challenges

    To my knowledge (I hope this is still correct by now):

    Attaching an existing Azure VM as a compute target requires a public IP. Even if your Azure ML workspace uses a private endpoint, the attach process defaults to SSH over the public IP. Azure ML does not currently support attaching a VM over a private IP only.
    So, your NSG and subnet config may be fine, but the service still needs that public IP to connect.

    VM not showing in Notebook compute options is also as expected. Attached VMs are only for submitting training jobs, not for interactive notebooks. Only Azure ML-created compute instances/clusters show up in the notebook UI.

    Recommendation: If you want a private-only setup, use a Compute Instance or Compute Cluster created in Azure ML Studio. These can live fully inside a VNet and support private networking properly.

    Hope that helps. Best regards! :)
