Under which deployment option do we specify the datastore to be used to store the virtual machines? ---

Hello @javieralaez Can you clarify what you mean with “deployment option”? Are you looking on the UI of OpenNebula? For Datastores management, I would suggest you to start from the documentation: [Datastores](https://docs.opennebula.io/7.0/product/cluster_configuration/storage_system/datastores/). At the bottom you’ll find the section for Sunstone. Regards, ---
