Hi!

Make sure you added the right parameter to the kernel command line, as per

"""
TL;DR: To make use of a serial console, just use console=ttyS0 on the kernel 
command line, and systemd will automatically start a getty on it for you.
"""

nice full tutorial on http://0pointer.de/blog/projects/serial-console.html

Bests,
