Create Azure Local VM image using image in Azure Storage account

Applies to: Azure Local, version 23H2

This article describes how to create virtual machine (VM) images for Azure Local using source images from Azure Storage account. You can create VM images using the Azure portal or Azure CLI and then use these VM images to create Arc VMs on Azure Local.

Prerequisites

Before you begin, make sure that the following prerequisites are completed.

Azure CLI

• Make sure to review and complete the prerequisites.

• For custom images in Azure Storage account, you have the following extra prerequisites:

  • You should have a VHD loaded in your Azure Storage account. See how to Upload a VHD image in your Azure Storage account.
  • Make sure that you're uploading your VHD or VHDX as a page blob image into the Storage account. Only page blob images are supported to create VM images via the Storage account.
  • If using a VHDX:
    • The VHDX image must be Gen 2 type and secure boot enabled.
    • The VHDX image must be prepared using sysprep /generalize /shutdown /oobe. For more information, see Sysprep command-line options.

• If using a client to connect to your Azure Local instance, see Connect to Azure Local via Azure CLI client.

• Make sure that you have Storage Blob Data Contributor role on the Storage account that you use for the image. For more information, see Assign an Azure role for access to blob data.

Add VM image from Azure Storage account

You create a VM image starting from an image in Azure Storage account and then use this image to deploy VMs on your Azure Local.

Azure CLI

Follow these steps to create a VM image using the Azure CLI.

Sign in and set subscription

1. Connect to a machine on your Azure Local.

2. Sign in. Type:

   az login --use-device-code
   

3. Set your subscription.

   az account set --subscription <Subscription ID>
   

Set some parameters

1. Set your subscription, resource group, location, path to the image in local share, and OS type for the image. Replace the parameters in < > with the appropriate values.

$subscription = "<Subscription ID>"
$resource_group = "<Resource group>"
$location = "<Location for your Azure Local>"
$osType = "<OS of source image>"
$imageName = "<VM image name>"
$imageSourcePath = "<path to the source image in the Storage account>"

The parameters are described in the following table:

Parameter	Description
subscription	Subscription for Azure Local that you associate with this image.
resource_group	Resource group for Azure Local that you associate with this image.
location	Location for your Azure Local instance. For example, this could be eastus.
imageName	Name of the VM image created starting with the image in your local share. Note: Azure rejects all the names that contain the keyword Windows.
imageSourcePath	Path to the Blob SAS URL of the image in the Storage account. For more information, see instructions on how to Get a blob SAS URL of the image in the Storage account. Note: Make sure that all the Ampersands in the path are escaped with double quotes and the entire path string is wrapped within single quotes.
os-type	Operating system associated with the source image. This can be Windows or Linux.

Here's a sample output:

PS C:\Users\azcli> $subscription = "<Subscription ID>"
PS C:\Users\azcli> $resource_group = "mylocal-rg"
PS C:\Users\azcli> $location = "eastus"
PS C:\Users\azcli> $osType = "Windows"
PS C:\Users\azcli> $imageName = "mylocal-storacctimage"
PS C:\Users\azcli> $imageSourcePath = 'https://vmimagevhdsa1.blob.core.windows.net/vhdcontainer/Windows_InsiderPreview_ServerStandard_en-us_VHDX_25131.vhdx?sp=r"&"st=2022-08-05T18:41:41Z"&"se=2022-08-06T02:41:41Z"&"spr=https"&"sv=2021-06-08"&"sr=b"&"sig=X7A98cQm%2FmNRaHmTbs9b4OWVv%2F9Q%2FJkWDBHVPyAc8jo%3D'

Create VM image from image in Azure Storage account

1. Select a custom location to deploy your VM image. The custom location should correspond to the custom location for your Azure Local. Get the custom location ID for your Azure Local. Run the following command:

   $customLocationID=(az customlocation show --resource-group $resource_group --name "<custom location name for your Azure Local>" --query id -o tsv)
   

2. Create the VM image starting with a specified marketplace image. Make sure to specify the offer, publisher, sku and version for the marketplace image.

   az stack-hci-vm image create --subscription $subscription --resource-group $resource_Group --custom-location $customLocationID --location $location --name $imageName --os-type $osType --image-path $imageSourcePath --storage-path-id $storagepathid
   

   A deployment job starts for the VM image.

   In this example, the storage path was specified using the --storage-path-id flag and that ensured that the workload data (including the VM, VM image, non-OS data disk) is placed in the specified storage path.

   If the flag is not specified, the workload data is automatically placed in a high availability storage path.

The image deployment takes a few minutes to complete. The time taken to download the image depends on the size of the image in Azure Storage account and the network bandwidth available for the download.

Here's a sample output:

PS > $customLocationID=(az customlocation show --resource-group $resource_group --name "mylocal-cl" --query id -o tsv)
PS C:\Users\azcli> az stack-hci-vm image create --subscription $subscription --resource-group $resource_Group --custom-location $customLocationID --location $location --name $imageName --os-type $osType --image-path $imageSourcePath --storage-path-id $storagepathid

5. The input parameters are validated. If the validations succeed, you can review the VM image details and select Create.

   

6. An Azure Resource Manager template deployment job starts for the VM image. The image deployment takes a few minutes to complete. The time taken to download the image depends on the size of the Marketplace image and the network bandwidth available for the download.

   

   You can track the image deployment on the VM image grid. You can see the list of the VM images that are already downloaded and the ones that are being downloaded on the system.

   To view more details of any image, select the VM image name from the list of VM images.

7. When the image download is complete, the VM image shows up in the list of images, and the Status shows as Available.

   

   If the download of the VM image fails, the error details are shown in the portal blade.

   

List VM images

You need to view the list of VM images to choose an image to manage.

Azure CLI

Follow these steps to list VM image using Azure CLI.

1. Run PowerShell as an administrator.

2. Set some parameters.

   $subscription = "<Subscription ID associated with your Azure Local>"
   $resource_group = "<Resource group name for your Azure Local>"
   

3. List all the VM images associated with your Azure Local. Run the following command:

   az stack-hci-vm image list --subscription $subscription --resource-group $resource_group
   

   Depending on the command used, a corresponding set of images associated with your Azure Local are listed.

   • If you specify just the subscription, the command lists all the images in the subscription.
   • If you specify both the subscription and the resource group, the command lists all the images in the resource group.

   These images include:

   • VM images from marketplace images.
   • Custom images that reside in your Azure Storage account or are in a local share on your system or a client connected to your system.

Here's a sample output.
