  • Planning and installing OpenNebula
  • Configuration and basic usage

Hands-ons Labs

Attendees will be grouped into groups of two people. Each group will receive a lab. Each lab consists of one OpenNebula frontend node and two hypervisors. It is important that every attendee is able to SSH (port 22 or port 443) to the machines. Each attendee should have his own laptop / machine, as this is a practical course with examples. The attendees will be the owners and administrators of their labs. They will be able to launch virtual machines, make configuration changes, debug problems, access the GUI and the CLI.


The target audience is devops and system administrators interested in deploying a private cloud solution, or in the integration of OpenNebula with other platform.

Skills Gained

  • Describe the features and benefits of using virtualization and clouds
  • Describe different architectures for a cloud that can be deployed with OpenNebula
  • Deployment and basic configuration OpenNebula
  • Basic operation of an OpenNebula cloud instance


No prior OpenNebula skills are required, but participants should have working knowledge of virtualization, networking and Unix/Linux systems.


The workshop includes hands-on exercises to be performed using attendee’s wifi-enabled laptops with remote Virtual Machines installed. The attendees will configure and operate their own OpenNebula cloud.
