  - Runs on a Fedora Host.

  - Outputs a qcow2 file.

* "CentOS >= 8":https://www.centos.org/: centos-build-opennebula-image.sh in "ungleich-tools":https://code.ungleich.ch/ungleich-public/ungleich-tools

  - Runs on a CentOS or Fedora host (with CentOS repositories imported by hand).

  - Outputs a raw file.
