Message: Required parameter 'hyperVGeneration' is missing (null) while creating a Managed Disk image from blob storage

Question

• Package Name: azure.mgmt.compute
• Package Version: v2020_06_01
• Operating System: ubuntu 18.04
• Python Version: Python 3.7

Describe the bug Instead of creating the disk it throws Message: Required parameter 'hyperVGeneration' is missing (null). error.

To Reproduce Steps to reproduce the behavior:

1. Run below code

compute_client = get_client_from_cli_profile(ComputeManagementClient)
async_creation = compute_client.images.create_or_update(
    '7AQVDL2J',
    'test',
    {
        'location': 'westeurope',
        'storage_profile': {
           'os_disk': {
              'os_type': 'Linux',
              'os_state': "Generalized",
              'blob_uri': 'https://bg09.blob.core.windows.net/vm-images/non-existent.vhd',
              'caching': "ReadWrite",
           }
        }
    }
) 

Expected behavior Disk should be created

Answer 1

I can reproduce your issue, to fix it, we need to add a hyper_vgeneration when you creating the image.

You could refer to the sample below, it works fine on my side.

from azure.mgmt.compute.models import DiskCreateOption
from azure.mgmt.compute import ComputeManagementClient
from azure.common.client_factory import get_client_from_cli_profile

compute_client = get_client_from_cli_profile(ComputeManagementClient)
async_creation = compute_client.images.create_or_update(
    'groupname',
    'test123',
    {
        'location': 'eastus',
        'storage_profile': {
           'os_disk': {
              'os_type': 'Linux',
              'os_state': "Generalized",
              'blob_uri': 'https://joystoragev2.blob.core.windows.net/vhds2/destDisk.vhd',
              'caching': "ReadWrite",
           }
        },
        'hyper_vgeneration': 'V1'
    }
)
image_resource = async_creation.result()
print(image_resource)
