How to Use miniONE to Deploy VMs on the Edge

Solution Verified in:

  • OpenNebula: 5.10


miniONE is OpenNebula’s simple evaluation tool for deploying an all-in-one installation based on the KVM hypervisor or on LXD system containers. The latest version of miniONE brings a new option that allows users to try OpenNebula’s edge computing features by using cloud resources at the edge from bare-metal infrastructure provider Packet.


You will need a Packet account, and in particular an API token and project ID that will be used to provision resources on Packet. Please follow the Packet's Getting Started Guide to create and retrieve them by using the Packet dashboard.



This screencast follows the procedure described in this article to deploy at the edge a dedicated server for OpenTTD, the well-known open source business simulation game.

Step 1: OpenNebula Frontend Installation

You will need one host for the OpenNebula frontend. It could be a physical host in your rack, your own VM or even a VM running in the public cloud. Choose either the Centos/RHEL or Ubuntu/Debian family, just ensure it is a relatively fresh and updated system.

For this demo, we decided to run the frontend on the small AWS EC2 instance, so let’s start in the AWS console. For the operating system it could be `Ubuntu Server 18.04 LTS`,for the instance type we could choose the `t2.micro` or give it little more memory by choosing `t2.small`. The only option you need to modify is adding some more storage, let’s say 25GB. Optionally you may allow accessing HTTP ports (80/443) to be able to easily connect to Sunstone, OpenNebula's WebUI.


Step 2: miniONE

As soon as your instance is ready, connect to it and download the tool

# wget ''

To start the edge deployment you will need to provide some details about the Packet resource. At least the packet API token and Packet project. Both can be easily found at



Then you should decide the location for your Edge deployment. For the first Packet node, we chose Sunnyvale, CA for which the code name is `sjc1`. Feel free to choose a different location – just be sure the required Packet plan is available there. In any case, miniONE will validate your parameters before it starts to deploy.

And finally you need to pick the size of the node – Packet calls this plan. We suggest keeping the `t1.small` default value. This is what Packet calls cloud killer, but if you want a different plan, provide it using the --edge-packet-plan parameter.

Now you should be ready to run.

# bash minione --edge packet --edge-packet-facility sjc1 --edge-packet-token [token] --edge-packet-project [project]

For the first time you will perhaps encounter the following error

Checking jq is installed  FAILED
Install jq package first

miniONE would like to validate all the Packet parameters and to parse the json output `jq` command is needed. In our case we will install it using

# apt update
# apt-get install jq

Now we will run the deployment again. While miniONE is doing its job, you should receive a similar output

### Checks & detection
Checking AppArmor  SKIP will try to modify

### Main deployment steps:
Install OpenNebula frontend version 5.8
Install ONEProvision
Configure IPAM Packet, alias IP mapping driver, VM hooks
Trigger oneprovision
Export appliance and update VM template

and finally end up with a similar successful report

### Report
OpenNebula 5.8 was installed
Sunstone [the webui] is runninng on:
Use following to login:
  user: oneadmin

### Packet provisioned
   0   PacketClu   0                  -                  - init

Now when all is done just wait for a little until OpenNebula monitors the Packet host and you can see it on. Check using

# onehost list
 0   PacketClu   0       0 / 400 (0%)     0K / 7.8G (0%) on

Step 3: Run the VM

At this point, you have a ready-to-use OpenNebula frontend connected with the KVM hypervisor on the Packet and you are ready to deploy your VMs. You can do it using the Sunstone frontend or just by typing

# onetemplate instantiate 0

For the demo purposes, we chose the default appliance to be our WordPress service app. So when your first VM is running, go to the public IP of the VM and you should get a bootstrapped WordPress webpage. To see the VM public IP address run

# onevm show 0 | grep ETH0_ALIAS0_IP=


However, you might choose a different virtual appliance for your case. Go to our public Marketplace and pick one of the systems. Be aware that you need to put an exact name to the parameter `--edge-marketapp-name`. For instance `CentOS 7 - KVM` is a valid option.

miniONE gives you an option to extend the deployment by adding additional hypervisor nodes at the edge. To do so simply add an option `--node` to the deployment command and run it again. For the second node, we chose the location to be Amsterdam, which has `ams1` code name.

# ./minione --edge packet --node --edge-packet-token [token] --edge-packet-project [project] --edge-packet-facility ams1

When the miniONE finishes, you should see 2 hosts now:

# onehost list
 1   PacketClu   0       0 / 400 (0%)     0K / 7.8G (0%) on    
 0   PacketClu   1    100 / 800 (12%)   768M / 7.8G (9%) on

Under the hood, miniONE uses the DDC tool called oneprovision, which also offers a command-line interface. To list the Packet resources, type

# oneprovision list
        ID NAME                      CLUSTERS HOSTS VNETS DATASTORES STAT           
642e1b04-d266-4ed6-abf4-906ca4a08898 PacketProvision-101              1     1     2          2 configured     
794e1810-a9f4-4047-8601-b4aad4a7d086 PacketProvision-100              1     1     2          2 configured

and to see the details

# oneprovision show 642e1b04-d266-4ed6-abf4-906ca4a08898

PROVISION 642e1b04-d266-4ed6-abf4-906ca4a08898 INFORMATION                      
ID      : 642e1b04-d266-4ed6-abf4-906ca4a08898
NAME    : PacketProvision-101
STATUS  : configured





Step 4: Pricing and Cleanup

If you choose the smallest AWS instance for the frontend as we did you should fit withing the Free tier eligible (up to 750hrs). The price of the Packet `t1.small` instance is $0.07 per hour. So even if you play with the deployment for quite a while you could hardly exceed $1.

Before you finish the evaluation, don’t forget to clean up your AWS EC2 instance as well as the Packet host. To delete the Packet you can use again the oneprovision command

# oneprovision delete [id] --cleanup
[root@minione-fe:~]$ oneprovision delete [ID] --cleanup

miniONE is a tool to really help newcomers get “up and running” with an OpenNebula environment. And now you’ve seen how easy it is to launch your own edge deployment or eventually extend your current setup with on-demand bare-metal resources at the edge.
