Terraform Configuration Files

resource "nutanix_virtual_machine" "vm" {
  name                 = "vm-ntnx"
  count                 = 1
  cluster_uuid       = data.nutanix_cluster.cluster.id
  num_sockets     = 1
  memory_size_mib   = 2048

  boot_type = "LEGACY"

  disk_list {
    data_source_reference = {
      kind = "image"
      uuid = data.nutanix_image.image.id
    }

Expected Behavior

VM creation with BIOS firmware.

Actual Behavior

│ Error: error waiting for vm (b635f363-bde0-4ba1-aec2-22be78543d83) to create: error_detail: INTERNAL_ERROR: Internal Server Error., progress_message: create_vm
│
│ with nutanix_virtual_machine.vm[0],
│ on main.tf line 36, in resource "nutanix_virtual_machine" "vm":
│ 36: resource "nutanix_virtual_machine" "vm" {

Steps to Reproduce

1. terraform apply

Important Factors

If you comment out boot_type it works properly.
If you output boot_type after vm is created without boot_type set it outputs empty values:

output "boottype" {
  value = nutanix_virtual_machine.vm.boot_type
}

boot_type = [
"",
]

It should show "LEGACY" (acorrding provider documentation) or "BIOS" (as shown on Prism UI).

Hi @brunobenchimol ,

1. when you setting boot_type, i would recommend to pass with boot_device_order_list . It's a requirement from create_vm . A disk_address, mac_address, boot device order must be specified for the non UEFI boot configuration .
2. Output shows empty values expected . If the value is not explicitly set, it falls back to default. when something is omitted from response, you can assume it takes on a default value.
