Disk change in VM Template doesn't take effect

[grossibr]

Description

Removing a disk from VM Template in terraform doesn't generate one.template.update in ONe, only a one.template.info request for the diff as there's no if d.HasChange("disk") condition in https://github.com/OpenNebula/terraform-provider-opennebula/blob/master/opennebula/resource_opennebula_template.go#L541C67-L541C67

Terraform and Provider version

Terraform v1.5.1 on darwin_arm64

• provider registry.terraform.io/opennebula/opennebula v1.3.0

Affected resources and data sources

opennebula_template

Terraform configuration

resource "opennebula_template" "instance-template" {
  name               = var.instance_template_name
  cpu                = var.cpu
  vcpu               = var.vcpu
  memory             = var.memory_gb * 1024
  permissions        = "660"
  sched_requirements = var.cluster_id
  context = {
    AXC_VMTYPE          = "cf"
    DNS                 = var.dns
    DNS_HOSTNAME        = "YES"
    NETWORK             = "YES"
    REPORT_READY        = "YES"
    SEARCH_DOMAIN       = var.search_domain
    START_SCRIPT_BASE64 = var.start_script_base64
    TOKEN               = "YES"
  }
  cpumodel {
    model = "IvyBridge-IBRS"
  }
  disk {
    dev_prefix = "sd"
    discard    = "unmap"
    image_id   = 11
    size       = 20480
  }
  features {
    guest_agent        = "YES"
    virtio_scsi_queues = "3"
  }
  os {
    arch = "x86_64"
    boot = ""
  }
  raw {
    data = "<console/>"
    type = "kvm"
  }
  graphics {
    listen = "0.0.0.0"
    type   = "VNC"
  }
  nic {
    network_id = var.network_id
    security_groups = [
      0,
    ]
  }
}

Expected behavior

only 20G disk should exist, any other disks in this template should be deleted:

  # module.instance-template["cf"].opennebula_template.instance-template will be updated in-place
  ~ resource "opennebula_template" "instance-template" {
        id                 = "70"
        name               = "cf"
        # (13 unchanged attributes hidden)

      - disk {
          - cache           = "writeback" -> null
          - dev_prefix      = "sd" -> null
          - discard         = "unmap" -> null
          - image_id        = -1 -> null
          - size            = 358400 -> null
          - volatile_format = "raw" -> null
          - volatile_type   = "fs" -> null
        }

        # (7 unchanged blocks hidden)
    }

Actual behavior

Apply completes successfully, reporting template change:

and Disk deletion does not take effect in ONe interface:

Steps to Reproduce

create Template with 2 disks or more, then delete one disk from terraform code and see if it takes effect in ONe console
