Create Image Templates (MCS for Nutanix AHV)

In this article:

You can create Image Templates to publish Layered Images to your target platform where you can then use the Layered Image to provision servers on your chosen publishing platform. An Image Template stores your Layer assignments, along with a Layer icon and description. You can easily edit an Image Template and use it to publish new versions of your Layered Images.

Prerequisites

• OS Layer (Required)

• Platform Layer (Required for cross-platform deployments)

  The Platform Layer contains the software required for publishing to your environment, in this case:

  • Nutanix Acropolis VM Mobility
  • Citrix MCS Device imaging tools

  The Platform Layer must have the same hardware settings as the OS Layer. You choose these settings when deploying the VM for the OS and Platform Layers.

• App Layers (Optional)

  You can create an Image Template without App Layers. This is useful for testing your OS Layer before using it to create App Layers.

Create an Image Template

To create an Image Template:

1. In the Unidesk Management Console (UMC), select the Images module, then click Create Template. This opens the Create Template wizard.
2. In the Name and Description tab, enter a Name for the template and notes in the Description field, so you can identify the template when choosing one for publishing a Layered Image.
3. In the OS Layer tab, select one of the Available OS Layers. If there is more than one Layer Version, the most recent version is selected by default. You can choose an older version by expanding the Layer and choosing a different one.
4. In the App Assignment tab, select the App Layers to include in the Layered Images that you publish using this template.

5. On the Connector page, select a Citrix MCS for Nutanix AHV Connector Configuration for the location where you want to publish the Layered Image.

   If you do not yet have a Connector Configuration for Citrix MCS for Nutanix AHV, add one. Click New, choose the Connector Type, and follow the instructions to Create a Connector Configuration.

6. In the Platform Layer tab, select a Platform Layer with the tools and hardware settings that you need to publish Layered Images to your environment. For details, click here.

7. On the Layered Image Disk page, edit the following fields, as needed:

   • (Optional) Layered Image Disk File name. Enter a name for the Layered Image Disk.
   • Layered Image Disk Size. The default disk size of 100 GB is recommended.
   • Layered Image Disk Format. The default disk format is VHD, but you can also select VMDK or QCOW2.
   • Elastic Layering - Controls whether Elastic Layering on this Layered Image is allowed. To allow Elastic Layers for users of this Layered Image, select Application Layers only. Otherwise, select None.
8. On the Confirm and Complete tab, enter any comments you would like for this layer, and click Create Template.

The new Template icon appears in the Unidesk Images module.
