Declare an existing VNet as a DevTest VNet

Hello,

I’ve a question concerning Devtest lab ressources management under Azure with Terraform.
I have declare a resource azurerm_dev_test_lab like this :

provider "azurerm" {
  features {
  }
  version = ">=2.0.0"
}

resource "azurerm_resource_group" "VNetResourceGroup" {
  name     = "VNet-ResourceGroup"
  location = "FranceCentral"
}

resource "azurerm_resource_group" "VMResourceGroup" {
  name     = "VM-ResourceGroup"
  location = "FranceCentral"
}

resource "azurerm_virtual_network" "VNet" {
  name                = "MyVnet"
  location            = azurerm_resource_group.VNetResourceGroup.location
  resource_group_name = azurerm_resource_group.VNetResourceGroup.name
  address_space       = ["10.0.0.0/16"]
}

resource "azurerm_dev_test_lab" "DevTestLab" {
  name                = "DevTestLab"
  location            = azurerm_resource_group.VMResourceGroup.location
  resource_group_name = azurerm_resource_group.VMResourceGroup.name
}

Now, I want to declare my existing VNet (aka MyVNet) as a dev_test_virtual_network but it seems that is not possible :frowning:
I can do it via Azure portal but not via Terraform …

Please could you help me and confirm or not this information ?

Regards.
