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,

[ovirt-users] Problem with Getty and Serial Consoles

2016-06-13 Thread Christophe TREFOIS 
Dear all,

I am running 3.6.6 and am able to select a Console, however, the screen is 
black.

On the hypervisor, I try to start getty service manually, and end up with 
following error in journal

I am running CentOS 7.2.

Does anybody have some pointers on what could be the issue here?

Thank you,
