2. Enable Confidential Computing (optional)

In order to enable Confidential Computing on our Compute Resource Node, you must:

1. Use an AMD CPU from the 8004 or 9004 families.
2. Ensure that your system supports confidential computing. We have only tested Ubuntu 24.04 so far.
3. Enable SEV and SEV-SNP in the BIOS.
4. Enable confidential computing in the aleph-vm configuration.

Enable SEV in the configuration of aleph-vm, by default in /etc/aleph-vm/supervisor.env. This is not the default yet.

ALEPH_VM_ENABLE_CONFIDENTIAL_COMPUTING=True

After launching the server you can check the endpoint
http://localhost:4020/status/config or https://<your-node-domain>/status/config and verify that ENABLE_CONFIDENTIAL_COMPUTING has the value true.
