As I mentioned to Wainer, my suggestion is to include a comment about ansible_become=yes and ansible_become_password= variables as some systems may need it. > +Build environment > +~~~~~~~~~~~~~~~~~ > + > +The ``scripts/ci/setup/build-environment.yml`` Ansible playbook will > +set up machines with the environment needed to perform builds and run > +QEMU tests.

After I updated the packages on the system, the playbook worked without problems. So, my suggestion is to add the "update = yes" here, or add a note in the documentation asking the user to update the system before running the playbook. Except for the above comment and Wainer's comments, it looks good to me. With these changes: Reviewed-by: Willian Rampazzo <willi...@redhat.com> Tested-by: Willian Rampazzo <willi...@redhat.com>
