OpenNebula image management¶

Images¶

We build our own images for the following distributions:

• Fedora >= 31: fedora-build-opennebula-image.sh in ungleich-tools
  - Runs on a Fedora Host.
  - Outputs a qcow2 file.
• CentOS >= 8: centos-build-opennebula-image.sh in ungleich-tools
  - Runs on a CentOS or Fedora host (with CentOS repositories imported by hand).
  - Outputs a raw file.

FIXME: other images? Are they provided by the OpenNebula project?
