Azure python vm create fails when trying to create image with custom image

VM create fails with is osDisk error: msrestazure.azure_exceptions.CloudError: Changing property 'osDisk.image.uri' is not allowed.

Code snippet is as follows:

 storage_profile=azure.mgmt.compute.models.StorageProfile(
            os_disk=azure.mgmt.compute.models.OSDisk(
                caching=azure.mgmt.compute.models.CachingTypes.none,
                create_option=azure.mgmt.compute.models.DiskCreateOptionTypes.from_image,
                name=OS_DISK_NAME,
                os_type='Linux',
                vhd=azure.mgmt.compute.models.VirtualHardDisk(
                    uri='https://{0}.blob.core.windows.net/vhds/{1}.vhd'.format(
                        STORAGE_NAME,
                        OS_DISK_NAME,
                    ),
                ),
                image=azure.mgmt.compute.models.VirtualHardDisk(
                    uri='https://xxxxxxxxx.blob.core.windows.net/vm-images/Centos67-Azure.vhd'
                ),
            )

image is defined in the python API and the URi defined works fine with the Azure CLI

API azure==2.0.0rc3

If it helps this is the transaction being sent to azure:

url: hps://management.azure.com/subscriptions/b97ddb69-f825-48b4-9e19-48eb3b4c8267/resourceGroups/dev-eu-vnet9-rg/providers/Microsoft.Compute/virtualMachines/centos67-api

The issue has been resolved. Turned out the error returned is somewhat misleading. The issue was that there was that the target disk already existed and therefore couldn't be modified (i.e. change property error).

Once the target had a unique name the process worked properly and I was able to create VMs from my custom image.

According to the document, the class StorageProfile construction function has three parameters include image_reference, os_disk and data_disk. The parameter image in your code should be the class azure.mgmt.compute.models.ImageReference, not the class azure.mgmt.compute.models.VirtualHardDisk.

As reference, here is the sample code from the document.

storage_profile=azure.mgmt.compute.models.StorageProfile(
    os_disk=azure.mgmt.compute.models.OSDisk(
        caching=azure.mgmt.compute.models.CachingTypes.none,
        create_option=azure.mgmt.compute.models.DiskCreateOptionTypes.from_image,
        name=OS_DISK_NAME,
        vhd=azure.mgmt.compute.models.VirtualHardDisk(
            uri='https://{0}.blob.core.windows.net/vhds/{1}.vhd'.format(
                STORAGE_NAME,
                OS_DISK_NAME,
            ),
        ),
    ),
    image_reference = azure.mgmt.compute.models.ImageReference(
        publisher=IMAGE_PUBLISHER,
        offer=IMAGE_OFFER,
        sku=IMAGE_SKU,
        version=IMAGE_VERSION,
    ),
)

Hope it helps. Any concern, please feel free to let me know.
