Creating a vdisk in a specified storage_container via APIv3

hello @all,

I tried to create a VM with a vdisk on a specified storage_container via APIv3. 

The JSON I entered:

{
  "api_version": "3.0",
  "metadata":{
		"kind":"vm"
	},
  "spec": {
    "cluster_reference": {
      "kind": "cluster",
      "uuid": "<uuid>"
    },
    "name": "<name>",
    "resources": {
      "disk_list": [
        {
          "storage_config": {
            "storage_container_reference": {
              "kind": "storage_container",
              "uuid": "<uuid>",
              "name": "<name>"
            }
          }
        },
        {
          "data_source_reference": {
            "kind": "image",
            "uuid": "<uuid>"
          }
        },
        {
          "disk_size_mib": 10000
        }
      ],
      "memory_size_mib": 4096,
      "nic_list": [
        {
          "nic_type": "NORMAL_NIC",
          "is_connected": true,
          "ip_endpoint_list": [
            {
              "ip_type": "DHCP"
            }
          ],
          "subnet_reference": {
            "kind": "subnet",
            "uuid": "<uuid>"
          }
        }
      ],
      "num_sockets": 1,
      "num_vcpus_per_socket": 4,
      "power_state": "ON"
    }
  }
}

After I send this, it did...nothing. I got no error or anything else.

When I remove this part, everything seems to run:

       {
          "storage_config": {
            "storage_container_reference": {
              "kind": "storage_container",
              "uuid": "<uuid>",
              "name": "<name>"
            }
          }
        },

I only found this but I need it for APIv3.

So, what did I wrong? Is it a syntax-issue by me or a bug? :)

Cheers and thanks for your answers
