ovirt_vm with template not create preallocated disk

[PedroSilvaUW]

Describe the bug

I made a template in ovirt with pre-allocated disk but when i point to this template in terraform the vm is created with thin-provisioning disk. Also i use a template_disk_attachement_override but not change anything

To Reproduce

If you can please provide the steps to reproduce the issue.

1. Terraform will perform the following actions:
   
   # module.temp02.ovirt_vm.vm["xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"] will be created
   + resource "ovirt_vm" "vm" {
     + clone                     = false
     + cluster_id                = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
     + effective_template_id     = (known after apply)
     + id                        = (known after apply)
     + memory                    = 2000000000
     + name                      = "terraform_hello_world"
     + placement_policy_affinity = "migratable"
     + placement_policy_host_ids = [
         + "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
       ]
     + status                    = (known after apply)
     + template_id               = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
   
     + template_disk_attachment_override {
         + disk_id      = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
         + format       = "raw"
         + provisioning = "non-sparse"
       }
   }

2. Error: Failed to create VM
   │ 
   │   with module.temp02.ovirt_vm.vm["xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"],
   │   on modules/vms/main.tf line 25, in resource "ovirt_vm" "vm":
   │   25: resource "ovirt_vm" "vm" {
   │ 
   │ generic_error: non-retryable error encountered while creating VM terraform_hello_world, giving up
   │ (Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. Thin provisioned template disks
   │ can not be defined as Raw.]". HTTP response code is "400". HTTP response message is "400 Bad

   Expected behavior

Create a vm form a template with preallocated disk. Is that possible manually.

Hey @PedroSilvaUW please set clone=true in order to use preallocated VMs, otherwise the preallocation will not work. This is an oVirt limitation and not related to the Terraform provider.

works :) thanks :100:
