Also set ``console=ttyS1`` in ``acrn.conf`` to match the SOS boot args.

UP2 serial port setting

=======================
|

|

The serial port (ttyS1) in the 40-pin HAT connector is located at ``serial PCI BDF 0:18.1``.

You can check this from the ``lspci`` output from the initial Clearlinux installation.
