For context: I want to automatically enable Intel SGX for every VM and LXC in Proxmox, but it doesn’t seem like there’s a way to do it using APIs AFAIK (so Terraform is out of the question unless I’ve missed something) other than editing the template for the individual LXC/VM.

I’d like to know if there’s a tool that can automate this. I could potentially write a shell script but I’d like to know if there’s something that’s mature software before I go do this. I have been reading about Packer, Vagrant and cloud-init but I don’t think this is something in their scope of usage.

Thanks!
