Create Azure Stack HCI VM image using images in a local share

Applies to: Azure Stack HCI, version 23H2

This article describes how to create virtual machine (VM) images for your Azure Stack HCI using source images from a local share on your cluster. You can create VM images using the Azure portal or Azure CLI and then use these VM images to create Arc VMs on your Azure Stack HCI.

Prerequisites

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

  • Make sure to review and complete the prerequisites.

  • For custom images in a local share on your Azure Stack HCI, you'll have the following extra prerequisites:

    • You should have a VHD/VHDX uploaded to a local share on your Azure Stack HCI cluster.
    • 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.
    • The image should reside on a Cluster Shared Volume available to all the servers in the cluster. Both the Windows and Linux operating systems are supported.

Add VM image from image in local share

You create a VM image starting from an image in a local share of your cluster and then use this image to deploy VMs on your Azure Stack HCI cluster.

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

Sign in and set subscription

  1. Connect to a server on your Azure Stack HCI system.

  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, 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 Stack HCI cluster>"
    $imageName = <VM image name>
    $imageSourcePath = <path to the source image>
    $osType = "<OS of source image>"
    

    The parameters are described in the following table:

    Parameter Description
    subscription Resource group for Azure Stack HCI cluster that you associate with this image.
    resource_group Resource group for Azure Stack HCI cluster that you associate with this image.
    location Location for your Azure Stack HCI cluster. For example, this could be eastus.
    image-path 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.
    name Path to the source gallery image (VHDX only) on your cluster. For example, C:\OSImages\winos.vhdx. See the prerequisites of the source image.
    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 = "myhci-rg"
    PS C:\Users\azcli> $location = "eastus"
    PS C:\Users\azcli> $osType = "Windows"
    PS C:\ClusterStorage\Volume1> $imageName = "myhci-localimage"
    PS C:\ClusterStorage\Volume1> $imageSourcePath = "C:\ClusterStorage\Volume1\Windows_K8s_17763.2928.220505-1621_202205101158.vhdx"
    

Create VM image from image in local share

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

    $customLocationID=(az customlocation show --resource-group $resource_group --name "<custom location name for HCI cluster>" --query id -o tsv)
    
  2. Create the VM image starting with a specified image in a local share on your Azure Stack HCI cluster.

    az stack-hci-vm image create --subscription $subscription --resource-group $resource_group --custom-location $customLocationID --location $location --image-path $ImageSourcePath --name $ImageName --os-type $osType --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 the local share and the network bandwidth available for the download.

Here's a sample output:

PS C:\Users\azcli> $customLocationID=(az customlocation show --resource-group $resource_group --name "myhci-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 --image-path $ImageSourcePath --name $ImageName --os-type $osType --storage-path-id $storagepathid
type="CustomLocation" --location $Location --name $mktplaceImage --os-type $osType --image-path $mktImageSourcePath

List VM images

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

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 cluster>"
    $resource_group = "<Resource group name for your cluster>"
    
  3. List all the VM images associated with your cluster. 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 the Azure Stack HCI cluster 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 cluster or a client connected to the cluster.

Here's a sample output.

PS C:\Users\azcli> az stack-hci-vm image list --subscription "<Subscription ID>" --resource-group "myhci-rg"

View VM image properties

You might want to view the properties of VM images before you use the image to create a VM. Follow these steps to view the image properties:

Follow these steps to use Azure CLI to view properties of an image:

  1. Run PowerShell as an administrator.

  2. Set the following parameters.

    $subscription = "<Subscription ID>"
    $resource_group = "<Cluster resource group>"
    $mktplaceImage = "<Marketplace image name>"
    
  3. You can view image properties in two different ways: specify ID or specify name and resource group. Take the following steps when specifying Marketplace image ID:

    1. Set the following parameter.

      $mktplaceImageID = "/subscriptions/<Subscription ID>/resourceGroups/myhci-rg/providers/Microsoft.AzureStackHCI/galleryimages/myhci-marketplaceimage"
      
    2. Run the following command to view the properties.

      az stack-hci-vm image show --ids $mktplaceImageID

      Here's a sample output for this command:

      PS C:\Users\azcli> az stack-hci-vm image show --ids $mktplaceImageID

      }
      PS C:\Users\azcli> 
      

Delete VM image

You might want to delete a VM image if the download fails for some reason or if the image is no longer needed. Follow these steps to delete the VM images.

  1. Run PowerShell as an administrator.

  2. Set the following parameters:

    $subscription = "<Subscription ID>"
    $resource_group = "<Cluster resource group>"
    $mktplaceImage = "<Markeplace image name>"    
    
  3. Remove an existing VM image. Run the following command:

    az stack-hci-vm image delete --subscription $subscription --resource-group $resource_group --name $mktplaceImage --yes
    

You can delete image two ways:

  • Specify name and resource group.
  • Specify ID.

After you've deleted an image, you can check that the image is removed. Here's a sample output when the image was deleted by specifying the name and the resource-group.

PS C:\Users\azcli> $subscription = "<Subscription ID>"
PS C:\Users\azcli> $resource_group = "myhci-rg"
PS C:\Users\azcli> $mktplaceImage = "myhci-marketplaceimage"
PS C:\Users\azcli> az stack-hci-vm image delete --name $mktplaceImage --resource-group $resource_group
