terraform-provider-xenorchestra: Cannot use cloud_config while creating VM

I’m currently facing an issue, where we can create a cloud config in XO (or have it created with resource "xenorchestra_cloud_config") but when used to initialize a new VM, it doesn’t get applied.

I’ve verified that:

• the desired template is working (when I create a VM manually in XO and use the template + the given cloud config, it works)
• the cloud config itself must be working as well (due to previous point)
• Terraform can create a working cloud config

What I’ve tried:

• manually creating the cloud config and fetching it with data "xenorchestra_cloud_config" "cc" and using that
• creating the cloud config with Terraform (resource "xenorchestra_cloud_config" "cc") and using that
• using hashicorp/cloudinit provider (data "cloudinit_config" "cloudinit_config"), passing the config into part.content and using that
• inlining the cloud config directly into xenorchestra_vm.cloud_config with newlines or <<EOF ... EOF

Nothing seems to work. I’ve tried running terraform apply with TF_LOG_PROVIDER=DEBUG and I’ve noticed that the inputted cloud config made it all the way to the RPC call:

(I tried to format this with line breaks)

However a bit later when we’re waiting for the VM to be created, I’m receiving logs like this (notice CloudConfig: ResourceSet:<nil>):

The result is:

• the machine is created properly
• the XO CloudConfigDrive is created
• the cloud config never runs during the boot and what is written in it doesn’t get executed
• log files /var/log/cloud-init[-output].log obviously don’t exist either

System info:

• Terraform version v1.3.8
• terra-farm/xenorchestra version 0.24.0
• XenOrchestra is self hosted
  • xo-server 5.109.3
  • xo-web 5.111.1
  • commit ee837
