We have published a new screencast featuring OpenNebula 3.4. The screencast starts with a pristine installation of OpenNebula 3.4 and creates a new VM from scratch by implementing the following steps using OpenNebula’s  Sunstone:

• Bootstrapping the Virtual Infrastructure
  • Creating a host
  • Creating a datastore
  • Creating a network and a user
• Creating a Virtual Machine from scratch
  • Registering a CD
  • Registering an empty image
  • Creating an installation template
  • Installing
  • Deploying the VM
  • Test-driving the VM

The most relevant pages of the documentation one should refer to after watching the screencast are:

• What is a Datastore?
• Contextualizing Virtual Machines
• Managing Virtual Machine Images
• Creating Virtual Machines
• Managing Virtual Machines

You can also download the Ubuntu 12.04 LTS (Precise Pangolin) VM that was created during the screencast from http://appliances.c12g.com/ubuntu-server-12.04/.
