How to Install Tripleo(Openstack on Openstack) UnderCloud on CentOS 7


Undercloud is a single node OpenStack installation deployed either in a Virtual machine or in bare metal server. The objective of undercloud is to install, test, manage and update its overcloud servers (Controller, Compute & Storage nodes). In Red Hat terminology undercloud is known as “Director“. Undercloud basically contains all the images that is required to deployed Overcloud Controller, Computes, Swift and Storage.

Overcloud is the actual functional cloud for any organization where all the Virtual Machines are created on compute nodes and handle all the workloads. In other words we can say overcloud provides the openstack services like Nova, Keystone , Horizon, Neutron, cinder, Glance, Heat & Ceilometer Services.

In this article we will demonstrate how to install TripleO undercloud or Director on CentOS 7 VM.

Following are the minimum system requirements for undercloud:

  • 16 GB RAM
  • 1 Quad Core CPU
  • 80 GB disk Space
  • 2 Nics
  • CentOS 7.x / RHEL 7.x

Below are my lab setup details:

  • CentOS 7 VM (Minimal Installation) is hosted inside the KVM hypervisor.
  • Two Interfaces are attached to VM (Provisioning & NAT)
  • Provisioning Network:
  • NAT Network:
  • IP Address on eth0 is and IP Address on eth1 is

To successfully install undercloud inside a virtual machine, you have to enabled Nested Virtualization in KVM hypervisor, if you not sure how to enable it, refer the below:

Let’s jump into the CentOS 7 VM and follow the below Steps:

Step:1) Set the Hostname and update /etc/hosts file

Run the hostnamectl command to set the hostname,

[[email protected] ~]# hostnamectl set-hostname ""
[[email protected] ~]# exec bash
[[email protected] ~]#

Add the following entries using the beneath command:

[[email protected] ~]# echo "" >> /etc/hosts

Update your system using below yum command and reboot once.

[[email protected] ~]# yum update -y && reboot

Step:2) Create non-root user (stack)

Run the beneath commands one after the another to create stack user and assign sudo rights to it. We will install undercloud using stack user only.

[[email protected] ~]# useradd stack
[[email protected] ~]# echo "enter_password_here" | passwd --stdin stack
[[email protected] ~]# echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack
stack ALL=(root) NOPASSWD:ALL
[[email protected] ~]# chmod 0440 /etc/sudoers.d/stack
[[email protected] ~]# su - stack
[[email protected] ~]$

Step:3) Enable required repositories for undercloud

Execute the below commands to enable and configured required repositories for undercloud installation.

[[email protected] ~]$ wget
[[email protected] ~]$ rpm -ivh python2-tripleo-repos-0.0.1-0.20190328140951.a7bc8dc.el7.noarch.rpm
[[email protected] ~]$ sudo -E tripleo-repos -b rocky current
[[email protected] ~]$ sudo yum -y install yum-plugin-priorities
[[email protected] ~]$ sudo yum install epel-release -y

Note : We can check the latest version of python2-tripleo-repos from RDO repository

Step:4) Install TripleO CLI package using yum command

[[email protected] ~]$ sudo yum install python-tripleoclient -y

Step:5) Copy & edit “undercloud.conf” sample file that suits to your env

[[email protected] ~]$ cp /usr/share/instack-undercloud/undercloud.conf.sample ~/undercloud.conf

Now edit ‘undercloud.conf‘ that suits to your environment, In my case I am adding the following content under “Default” Section

[[email protected] ~]$ vi undercloud.conf
local_ip =
undercloud_public_vip =
undercloud_admin_vip =
local_interface = eth1
masquerade_network =
dhcp_start =
dhcp_end =
network_cidr =
network_gateway =
inspection_iprange =,
generate_service_certificate = true
certificate_generation_ca = local

Save and exit the file.

Step:6) Start undercloud installation using openstack command

Now start undercloud installation using below openstack command,

[[email protected] ~]$ openstack undercloud install

Once the installation is completed successfully, we will get the output something like below


Verify the OpenStack Service list

[[email protected] ~]$ source stackrc

This confirms that undercloud has been installed successfully. In the next article we will demonstrate how to import overcloud images in under cloud and how to create inventory file for overcloud servers and then we will see how we can deploy overcloud servers via undercloud.

    Hello Pardeep, actually I’m having issue while some sort of issues while setting the Networking Block for VM like Provisioning and NAT. I’ve done every thing, Enabled Nested Virtualization, Configure IP Forwarding but I don’t have the Network Connectivity between my VM and Host. even I’ve used ‘tcpdump’ to capture the traffic and I’ve got the result regarding ‘ARP’. both systems are not able to resolve ARP Requests. so plz help me to solve this issue
    My Setup : RHEL 7.3 as Host as well Guest( for UnderCloud )

  6. Jay says:

    Hello Pradeep, I have some confusion. Could you share about how to create Provisioning & NAT Network on KVM host ? Do physical interfaces need to be attached to the bridges belonged to Provisioning & NAT Network ? And do bridges need to be created with IPs ? Many thanks!

    • Pradeep Kumar says:

      Hi Jay,

      You need to create two networks i.e Provisioning and NAT using ‘virsh net-define’ on your KVM hypervisor, Specify the IP address range in the networks xml file,

      virsh net-define /tmp/provisioning.xml

      After creating the networks, attach these network to undercloud Interfaces via Bridges.

      • Jay says:

        hi Pradeep, I have successfully completed undercloud & overcloud installation. Thank you very much! !
        And I have other confusions. Thanks in advance.
        (1) Would it be OK if Provisiong Network not created using virsh net-define and I just create a bridge assigning IP address and then make undercloud & overcloud interfaces attached to the bridge ? if not, why ?
        (2) When configuring neutron, you know, which overcloud compute node interface should be attached to the bridge that will be configured in ”bridge_mappings = :” in openvswitch_agent.ini ? That means which interface is used to openstack VM network ?

    You need to downgrade leatherman packages by “yum downgrade leatherman”.
    I’m using i.e. rpm -qa | grep leatherman

    • danang says:

      the downgrade leatherman is complete, but if run hit again $openstack undercloud install, the process install will be trigger to update package again, and so occur fail back
