 There are a few exceptions and limitations to choosing a VM size:
 * Some VM series are not supported in Azure Machine Learning.
-* Some VM series are restricted and need to be specifically enabled before they can be allocated.
+* Some VM series are restricted and need to be specifically approved before they can be provisioned. To do this, file a support ticket for a quota increase request for the VM series you want to use.
