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)**

Traceback (most recent call last):

what can be the problem here?

Thanks,

libcloud/compute/drivers/azure_arm.py の create_node と _get_instance_vhd から始め、次にステータス 400 を返す AzureBlobsStorageDriver の呼び出しを追跡します。示されている Azure ARM インスタンス作成フローを再現し、失敗している VHD 名または blob リクエストを特定します。原因に対して具体的な対応が可能で、インスタンス作成パスがそれを正しく処理できれば完了です。
