Hello Petr,

the "unrecognized arguments" is the best hint here and it means you most probably don't have the "yaml_to_mux" installed. You can list installed plugins by "avocado plugins" or, in your case, by running "rpm -qa | grep avocado". As suggested in http://avocado-framework.readthedocs.io/en/52.1/GetStartedGuide.html you need to install  "python-avocado-plugins-varianter-yaml-to-mux" plugin which implements the `-m` option.

Note with more recent Avocado you get to chose from either "yaml_to_mux" or "pict" but in LTS you only have the "yaml_to_mux" varianter plugin available.

Do you think we can improve a bit? We moved the optional_plugins documentation to special section to emphasize they are not core, maybe the "optional_plugins" section header can be a bit better. Or do you think something like "-m option is not supported, do you have all plugins installed (use 'avocado plugins' to list them)" would help?

Regards,
Lukáš
