Nutanix OpenStack Part I – Deployment

This will be the first blog post in a series that will cover the Nutanix OpenStack solution and what could be better than starting with the deployment. I will not spend much time explaining the architecture but i’ll mention the three main components in the Nutanix OpenStack solution:

  • Acropolis OpenStack Services VM (OVM) – This is the VM we will create later in the blog post and it includes both the below components in my case. You can use another OpenStack controller if you prefer but in this demo purpose case i don’t have any requirements that can justify that.
  • OpenStack Controller (OSC) – The OpenStack controller manage the OpenStack API calls and provides e.g. the API and UI capabilities.
  • Acropolis OpenStack Driver – The OpenStack Controller sends instructions to the Acropolis OpenStack drivers which translates them to Acropolis API calls.


First a few things you need before we can complete the deployment since it involves connecting the OVM to an existing Nutanix Acropolis Hypervisor (AHV) cluster.

  • Install an AHV based Nutanix cluster.
  • Download the OVM from the Nutanix Portal via the Downloads -> Tools & Firmware dropdown.
    • Search for Nutanix OpenStack Image and download the qcow2 file

  • Upload the Image to the existing Nutanix cluster Image Configuration formerly known as Image Service using the following procedure:
    • Start Image Configuration via the upper right Gear Icon -> Image Configuration

    • Click the Upload Image button
      Screen Shot 2016-03-18 at 02.03.09
    • Give the Image a Name, Provide an Annotation, Select Disk as Image Type, Select Container and finally select the downloaded file before pressing the Save icon.

When done it’s time to start deploying the OVM.


As with any other Nutanix solution the OpenStack one is also very easy to deploy. Follow the below steps and you are up and running a few minutes after the download has completed.

  • Create the OVM using the qcow2 file via the VM -> Table view and pressing the light green Create VM icon upper right corner
    • Give the VM a Name, configure 4 vCPUs, configure 16 GB RAM

    • Create a disk using the Clone From Image Service options, select the recently uploaded OVM-Img file and click Add.

    • Create a NIC meaning select a VLAN ID in the drop down box and click add.

    • When VM is created, power it on and launch the console
  • Configure the OVM. There are only three commands that you need to run to setup the OVM but please refer to the Implementation guide for additional information and potential configuration steps regarding compute resource calculation, Nutanix Container to be used among other things.
    • Add Nutanix OVM
      • ovmctl –add ovm –name ovm01 –ip –netmask –gateway –nameserver –domain vcdx56.local
        Important: there are two minus signs before each argument meaning —

        • IP is the IP of the OVM we just deployed and the rest is pretty self explaining
    • Add OpenStack Controller
      • ovmctl –add controller –name ovm01 –ip
        Important: there are two minus signs before each argument meaning —

        • OVM is still the OVM we just deployed. This is where you can configure another Controller if needed.
    • Add the first Nutanix Cluster
      • ovmctl –add cluster –name npx5 –ip –username admin –password nutanix/4u –container_name CTR01
        Important: there are two minus signs before each argument meaning — Screen Shot 2016-03-18 at 03.01.48

        • This is where we add the Nutanix AHV based cluster as an OpenStack hypervisor. Since i don’t have a Nutanix Container called default i need to specify the Nutanix Container name using –container_name
  • Verify the configuration using the ovmctl –show command and make sure there are no errors and that the configured Nutanix Cluster is displayed correctly

  • Now it’s time to access the UI.
    • Browse to using and log in using admin/admin

    • This is the Home screen when loggin in as admin

    • Verify the Hypervisor, the Nutanix cluster is successfully displayed in the UI

Yes, i know i’m employees by Nutanix but this is by far the easiest and fatest OpenStack deployment i have ever seen. The footprint is just one single VM using 4 vCPUs and 16 GB Memory compared to multiple VMs for many other solutions.
