Unable to find a name for a VHD to use for instance

Hi,

I'm trying to create a simple instance on Azure and I'm getting the exception as attached bellow.
I tried to consult with Azure support but they didn't find something problematic with all definitions that related to my Azure account.

Please note that I'm getting the location, the size and the image properly from the defined driver.

**from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.AZURE_ARM)
driver = cls(tenant_id=tenant_id,
subscription_id=subscription_id,
key=app_id, secret=secret)
loc = [l for l in driver.list_locations() if l.id == default_zone ][0]
size = [s for s in driver.list_sizes(location=loc) if s.name == base_instance_size ][0]
ami = driver.get_image('Canonical:UbuntuServer:16.04-LTS:latest', location=loc)
node = driver.create_node("test_node",
... size=size,
... image=ami,
... location=loc,
... ex_resource_group=resource_group,
... ex_storage_account=storage_account,
... ex_network='iavn1011126702',
... ex_subnet='iasub1011126702',
... auth=None)**

what can be the problem here?

Thanks,

Empieza en libcloud/compute/drivers/azure_arm.py, en create_node y _get_instance_vhd, y luego sigue las llamadas de AzureBlobsStorageDriver que devuelven el estado 400. Reproduce el flujo mostrado de creación de instancias de Azure ARM y determina el nombre de VHD o la solicitud de blob que falla; se considera terminado cuando la causa permite una acción concreta y la ruta de creación de instancias la gestiona correctamente.
