Overview of Global Images


Applies to: Nerdio Manager for MSP (NMM)


 

In this article, we will cover:

Overview

The Global Images module provides centralized management for desktop images that can be made available to any or all of your customer accounts. This allows you to make customized images with applications and settings that you re-use in many customer environments without duplicating effort with each new account.

Navigate to the Global Images module by clicking on Global Images in the left menu while at the MSP level of NMM (not in a customer account).

The drop down arrow to the right of an image shows options available for that image:

You can either "Power on" / "Power off", "Restart", "Clone or "Delete" an existing image from this dropdown control. In the first column you will see the name of the image and an icon representing if the image is powered ON or OFF:

Add an image from an existing VM

Click the "Add from Azure VM" button:

and enter the required details:

Name: Type a name for your image (Note: This is a mandatory field)

Description: Type a short description for your image

SAS URL: Paste the SAS URL link exported from the source VM’s managed disk. To generate the SAS URL, go to Azure Portal and find the source VM you want to import as an image. Stop it and go to its managed OS disk object. Click on Disk Export under the Settings section. Type in the expiration duration in seconds (be sure it’s at least several hours for the copy process to complete) and click Generate URL.

Network: Select network that VM will be connected to. The selected network will also determine the Azure region of the VM.

OS: Select the OS installed on the source VM being imported. EVD = Enterprise Virtual Desktop (aka Windows 10 multi-session).

VM SIZE: Select size of the Desktop Image VM. This does not impact the size of session host VMs created based on this Desktop Image in the future.

OS SIZE: Select OS Disk type and size. This does not impact the OS Disk type of session host VMs created based on this Desktop Image in the future.

Resource Group: Select resource group that will contain the VM.

Create image VM as Gen2: By default, desktop image VMs are created as Gen1. Learn more about differences between Gen1 and Gen2 VMs

Join to AD: Join the image VM to Active Directory

Do not create image object: Create Desktop Image VM only but do not create an image object.
You will need to create the image object by clicking the "Power off and set as image" button after the VM is created before this Desktop Image can be used for session host creation. Skipping image creation allows for changes to be made to the VM before it is converted to an image.

Enable time zone redirection: Enabling time zone redirection on the image allows each user to see their local device's timezone inside of their WVD desktop session.

Set time zone: Set the time zone on the image VM

Uninstall FSLogix app: Use this option if FSLogix app is already installed in the base image and you want to remove it in order to allow Nerdio Manager to manage FSLogix.

Uninstall WVD agent: Use this option if you’re creating an image from an existing WVD session host where the WVD agent has been previously installed.

Shared Image Gallery: Select an existing Shared Image Gallery or create a new one. Only one SIG can be selected.

Azure Regions: Select Azure regions where the Global Image version should be replicated. The current Azure region must be part of the selection.

Provide custom credentials for a local administrator user: Enable this option to specify local admin credentials to be created on the image VM

 

Click OK to create the image VM from your source OS disk.

 

Add an Image from the Azure library

Click "Add from Azure library" button and enter the required details

Name: Type a name for your image (Note: This is a mandatory field)

Description: Type a short description for your image

Network: Select network that VM will be connected to. The selected network will also determine the Azure region of the VM.

Azure Image: Select Azure Marketplace Library image based on Windows operating system supported by WVD. EVD = Enterprise Virtual Desktop (aka Windows 10 multi-session). Office ProPlus contains a pre-installed Office 365 version of ProPlus that will be activated as users with appropriate licensing log into the desktop.

VM SIZE: Select size of the Desktop Image VM. This does not impact the size of session host VMs created based on this Desktop Image in the future.

OS SIZE: Select OS Disk type and size. This does not impact the OS Disk type of session host VMs created based on this Desktop Image in the future.

Join to AD: Join the image VM to Active Directory

Do not create image object: Create Desktop Image VM only but do not create an image object.
You will need to create the image object by clicking the "Power off and set as image" button after the VM is created before this Desktop Image can be used for session host creation. Skipping image creation allows for changes to be made to the VM before it is converted to an image.

Enable time zone redirection: Enabling time zone redirection on the image allows each user to see their local device's timezone inside of their WVD desktop session.

Set time zone: Set the time zone on the image VM

Shared Image Gallery: Select an existing Shared Image Gallery or create a new one. Only one SIG can be selected.
Azure Regions: Select Azure regions where the Global Image version should be replicated. The current Azure region must be part of the selection.

Provide custom credentials for a local administrator user: Enable this option to specify local admin credentials to be created on the image VM

Click OK to create the image VM.

 

 

Updating a Global Image

To make changes to a global image, first power it on. Then connect to the VM via remote desktop and make any required changes to the machine, such as installing software or updates. When finished, click Power off and set as image

Select the Shared Image Gallery and regions you would like the new image deployed to. 

Save current image as a backup: Selecting this option will retain the existing image as a standalone object and not overwrite it with the new one. This image will not be visible or manageable via Nerdio Manager so be sure to delete it manually when no longer needed to avoid unnecessary Azure storage costs. The current image is stored in Shared Image Gallery and it will be retained with an older version number. To re-use it again in Nerdio Manager, delete the newer version and the older one will be used automatically.

Leave desktop image VM running: Checking this option will leave the VM running after the set as image task completes. This is useful if you want to push OS and application updates to the running VM.

 

Assigning an image to accounts

Once you have a Global Image set up and configured, you will want to assign that image to your accounts. To do so, open the dropdown menu next to the image and select Assign accounts.

Select accounts you wish to assign to this image. By default, the image will be replicated to the region of the selected accounts. Check the "Skip image replication" box to override this behavior.

Once assigned, the image will be available in the selected accounts to use in host pools.
