OpenNebula is a mature and stable cloud software stack that lets you get running quickly and scales from a single node cloud to thousands of physical nodes. It can be used to build a private, public or a hybrid cloud.

Packages for OpenNebula are now available locally within centos.org and we publish images that are directly usable within any OpenNebula instance.

QuickStart

To get OpenNebula setup on your own hardware, we have a QuickStart guide that will help you get running in a few minutes.

Images

1. Image Notes

• These images are built for a 10GB disk size
• Each image download tarball contains
  • The image file itself in the defined format ( usually qcow2 )

  • An image definition file to register that image using the oneimage command

  • Template files for micro, small, medium and large instance types for the image ( note that you will need to have already setup the virtual network, and have the vnet name handy to include with these templates ) to use with the onetemplate command

2. Known Issues

• Images are built with firewall turned on, with only ssh allowed to connected in. On a Cloud instance where the access is controlled via security and network policy, this might not be an ideal state.
• We need to ensure that there is a CONTEXT / user-data snippet in the image definition file that allows users to insert their own root's authorized_keys ; this does not appear to be working presently
• We should ship some blank 10GB, 20GB and 50GB disk images, that have been pvcreated to match the included lvm setup in the images, making it trivial to add more storage on the fly to the existing images.
• Ensure a CONTEXT / user-data snippet exists for users to control SELinux
