How to specify availability zone when creating VM through Azure SDK

Question

I'm using the ComputeManagementClient in Azure's Python SDK to create a virtual machine. (Specifically, begin_start in VirtualMachinesOperations, found here.) However, I don't see an option to specify an availability zone -- only the resouce_group_name.

Is there some way to specify the availability zone when creating the VMs?

I've gone through the docs but I can't seem to find any mention of this functionality. I do know the Azure CLI supports this -- unsure why the SDK doesn't.

Answer 1

I created a VM through Azure Python SDK with a specified availability zone.

from azure.mgmt.network import NetworkManagementClient
from azure.mgmt.resource import ResourceManagementClient
from azure.identity import DefaultAzureCredential
from azure.core.exceptions import HttpResponseError

try:
    # Set up the Azure API clients
    subscription_id = 'subscription_id' # Update with your subscription_id
    credentials = DefaultAzureCredential()

    network_client = NetworkManagementClient(credentials, subscription_id)
    compute_client = ComputeManagementClient(credentials, subscription_id)
    resource_client = ResourceManagementClient(credentials, subscription_id)

    resource_client.resource_groups.create_or_update(
        resource_group_name,

    print(f'Created resource group: {resource_group_name} in location: {location}')

    # Define NIC parameters

    print(f'Created subnet: {subnet_name}')

    # Create a NIC
    nic = network_client.network_interfaces.begin_create_or_update(
        resource_group_name,
        nic_name,
        {
            'location': location,

    # Specify the availability zone
    availability_zone = '1'  # Change this to the desired zone (e.g., '1', '2', or '3')

    # Create a new VM with an availability zone and the created NIC
    vm = compute_client.virtual_machines.begin_create_or_update(
        resource_group_name,

                }
            }
        }
    )

    vm.result()

    print(f'Created VM: {vm_name} in availability zone {availability_zone}')

except HttpResponseError as ex:
    print(f"HTTP Response Error: {ex}")
except Exception as e:
    print(f"An error occurred: {e}")
