How would I automate (VM/LXC)-agnostic templates in Proxmox without creating golden images? (lemmy.world)

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!

Intel SGX requires for me to set a CPU flag in the .conf file. For now, it's a shell script and I can do it with Ansible, but I'd like to not have to do such half-baked measures

I see, agree with you that it should be supported by the terraform provider if it is at the VM .conf level... maybe a new attribute in https://registry.terraform.io/providers/Telmate/proxmox/latest/docs/resources/vm_qemu#smbios-block? I would start by requesting this feature in https://github.com/Telmate/terraform-provider-proxmox/issues, and maybe try to add it yourself? (scratch your own itch, fix it for everyone in the process). Good luck
