Uploading an image to a Nutanix AHV cluster

To be able to deploy virtual machines on your cluster, you will need images that are available to launch your installations and here is the procedure to follow.

Before you start

An image uploaded via Prism Element can be imported to Prism Central. The reverse is not possible.

An image uploaded or imported via Prism Central is visible but not editable on Prism Element.

An image uploaded via Prism Element can only be used by the cluster to which it was uploaded.

An image downloaded via Prism Central can be used by all clusters managed by this Prism Central

Nutanix provides compatibility with images in the following formats:

  • RAW
  • VHD
  • VHDX
  • VMDK
  • VDI
  • OVA
  • ISO
  • QCOW2

Download via Prism Element

To upload an image via Prism Element, connect to the web interface using your credentials, then navigate to the “Settings > Image Configuration” menu:

Image Configuration menu in Prism Element settings

Click Upload Image:

Upload Image button in Image Configuration

Complete the “Name”, “Image Type”, “Storage Container” fields, select the image you wish to transfer then click on “Save”:

Image list in Prism Element Image Configuration

Wait during the transfer and then while your image is processed by the cluster. Its status must be “ACTIVE” for it to be operational:

VirtIO 1.2.3 image being processed, still inactive
VirtIO 1.2.3 image now active

Download via Prism Central

The process for transferring an image through Prism Central is essentially identical to that of Prism Element.

Connect to the web interface then navigate to “Compute & Storage > Images” and click on “Add Image”:

Add Image button in the Prism Central Images menu

Click on “Add File”, select the image you want to transfer, fill in the description then click on “Next”:

Adding the image file in Prism Central

On the next screen, select the image placement mode based on your environment. In most cases, the default method “Place image directly on clusters” will do the trick, click “Next”:

Image placement method and cluster selection

Wait while the cluster transfers and processes the image.

Import images from Prism Element to Prism Central

On the image management page on Prism Central, click “Import Images”:

Import Images button in the Prism Central Images menu

Then select the transfer method that suits you:

Import Images window: all images or images on a cluster

“All images” will repatriate all the images from all the clusters managed by Prism Central

“Images on a cluster” will allow you to select the cluster(s) and source image(s) on a case-by-case basis.
