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,

Inizia in libcloud/compute/drivers/azure_arm.py, in create_node e _get_instance_vhd, quindi segui le chiamate di AzureBlobsStorageDriver che restituiscono lo stato 400. Riproduci il flusso mostrato di creazione dell'istanza Azure ARM e determina il nome VHD o la richiesta blob che fallisce; il lavoro è completato quando la causa consente un'azione concreta e il percorso di creazione dell'istanza la gestisce correttamente.

Scritto dal modello di indicizzazione a partire dal testo della issue.
