Description

Hello

I’m running into an issue deploying an AKS cluster with a new generation of virtual machines available in Azure. I am using the Standard_D8ads_v6 VM size. The same setup works fine with Standard_D8ads_v5.

Here’s the error I’m getting:

(BadRequest) Code="BadRequest" Message="The selected VM size 'Standard_D8ads_v6' cannot boot 
Hypervisor Generation '1'. If this was a Create operation please check that the Hypervisor Generation of 
the Image matches the Hypervisor Generation of the selected VM Size. If this was an Update operation 
please select a Hypervisor Generation '1' VM Size. For more information, see https://aka.ms/azuregen2vm"

I was able to create the node pool using the Azure CLI with this command:

az aks nodepool add --cluster-name cluster-eus1 --resource-group cluster-eus1 \
  --name test --node-osdisk-type Ephemeral --node-vm-size Standard_D8ads_v6 \
  --node-count 1 --os-type Windows --os-sku Windows2022 --aks-custom-headers UseWindowsGen2VM=true

But I need a Terraform-based solution to achieve the same result.

Thanks!
