title: Running multiple schedulers in Airflow 2.0 on same machine
body: <p>I understand that Airflow 2.0 now supports running multiple schedulers concurrently for HA. Can I run multiple schedulers on the <strong>same machine</strong> (VM)? Do I do it just by running <code>airflow scheduler</code> twice if I want 2 schedulers, without configuring anything else?</p>
