Build VM Images Using OneApps Toolset

Images are the backbone of any Virtual Machine. OpenNebula supplies vanilla OSes via the official Marketplace, but you might want to have a customized image with preinstalled software, OS-level tuning or any other adjustments. In order to achieve that you can leverage OneApps repository.

Agenda

What to expect from this training:

• Going through the basics of OneApps.
• Build a custom Image.
• Run a VM from this Image.
• A quick glimpse into an Appliance Building process.
