In v2.7, the ``acrn-dm`` command line parameter ``--cpu_affinity`` is now mandatory
when launching a User VM. If the launch XML settings, used to generate the launch
scripts, do not specify a ``cpu_affinity`` value, the ACRN Configurator will look for
it from the scenario XML settings. Verify that your existing launch scripts
specify this ``--cpu_affinity`` parameter as ``acrn-dm`` will now complain if it's
missing.
