12:15-13:45: Hands-on Part I: OpenNebula in Action

Juan Montiel, OpenNebula Systems. This hands-on tutorial will give an overview of how OpenNebula is used to build and operate private clouds. The attendees will build, configure and operate their own OpenNebula cloud.

13:45 – 14:30: Lunch

14:30-16:30: Hands-on Part II: OpenNebula in Action


  • Configuration and basic usage
  • An introduction to cloud computing with OpenNebula
  • The architecture of the cloud
  • Planning and installing OpenNebula
  • Virtualization hosts management
  • Basic datastore configuration
  • Basic virtual network creation
  • VM Template creation & instantiation


This is an interactive course, where the attendees operate on their own labs with a 3-node OpenNebula cloud, which are provided during the course. OpenNebula provides an abstraction layer on top of the infrastructure and technologies deployed in the datacenter. In order for the attendees to get the best understanding possible of OpenNebula as a whole, the labs used during the course make use of the most common open-source technologies that can be used to deploy an OpenNebula cloud. For example, the hypervisor technology used during the course will be KVM, shared file-system for storage, and regular linux bridges and linux firewall for networking. Other technologies supported by OpenNebula will be addressed and discussed as well.


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 instructor will rely on a set of PDF documents that will be explained throughout the course. These documents will be made available to the attendees right at the very beginning of the course. Attendees need a laptop to connect to their hands-on labs.

16:30: Open Space

This is a session for attendees to gather and discuss passionate questions, burning ideas, features, integrations or any topic of their choice, in an informal and tech-friendly environment, with other passionate and interested people. There is no preplanned list of topics, only time slots and a space in one of the meeting rooms where interested participants propose topics and pick time slots.
