MiniONE is an easy to use deployment tool for the OpenNebula KVM evaluation environment. All necessary components to manage and (locally) run the virtual machines are installed and configured on your dedicated physical host with just a single command run.
- dedicated physical host supporting hardware virtualization
- min. 2 GiB RAM
- min. 20 GiB free space on disk
- operating system CentOS 7, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 18.10 or Debian 9
- fresh default install of the operating system with the latest updates
- privileged user access (
Download the latest release of the
minione script, run it and follow the instructions from the terminal:
sudo bash minione
If the deployment ends succesfully, you now have your OpenNebula all-in-one evaluation environment ready to use! On the terminal, you'll see a deployment report with login information.
- enable OpenNebula repository
- install OpenNebula frontend and KVM hypervisor
- prepare networking for virt. machines (bridge
- configure firewall to provide NAT for virt. machines
- run private DNS server for virt. machines (
- start OpenNebula and prepare user, virt. networks, datastores
- import CentOS 7 virtual machine appliance
The evaluation deployment tool comes with default parameters suitable for most cases. You can list all the deployment parameters by running:
sudo bash minione --help
Start a verbose deployment and set own password for the default OpenNebula user:
sudo bash minione --verbose --password MySecretPassword
Specify OpenNebula virtual private network IP range for new deployment:
sudo bash minione --vnet-address 192.168.100.0 --vnet-gateway 192.168.100.1 --vnet-ar-ip-start 192.168.100.2
Try the Admin View in the Sunstone GUI
After the minione finishes, the first thing we are going to do is to log in as oneadmin to take a look at the Admin View of Sunstone, which has more options than the other Sunstone views for a regular users.
To login to Sunstone open your browser at
http://[ ip ]:9869. You should receive the login information from the minione report.
Take a look at all the already bootstrapped resources in the Sandbox.
Try the Cloud View
With the Admin View you can do anything in OpenNebula, but you don’t want all those options for the final users! Switch to the Cloud View to see how a final user will see OpenNebula:
The Cloud View interface is much simpler and targeted at end users.
Create a new Virtual Machine by clicking the
+ button. Select the only available template and click
After clicking create you will be taken to the dashboard where you can see your running VMs.
You can click on your VM and manage it: access it through VNC, Save its state, Reboot it, etc:
Clicking on the Console icon will let you login into the VM. The default credentials are:
Login: root Password: opennebula
With the oneadmin role you can customize what your cloud users can do and see.
Quick Overview of the CLI Interface
You need to connect to the sever either using the web console or using ssh. OpenNebula runs as the oneadmin user, and the main administrator should run commands as that user, therefore the first thing you need to do is to switch to oneadmin:
su - oneadmin
From the oneadmin account you can see all the already bootstrapped resources:
There is one network created
$ onevnet list
You can see the leases and the specific configuration of the network
$ onevnet show 0
A Centos image has been created
$ oneimage list
A Virtual Machine template is registered
$ onetemplate list
You can see the template configuration if further detail
$ onetemplate show 0
This is just a quick overview to get you started with OpenNebula. If you liked it, you may want to check the OpenNebula documentation for more information on how to deploy OpenNebula in your infrastructure and a detailed version of the OpenNebula features.
