Centos 6, 7
To get to see bootloader:
grubby --update-kernel=ALL --args="console=ttyS0"
ON Centos 6 you need to create /etc/init/ttyS0.conf:
stop on runlevel[S016] start on stopped rc RUNLEVEL=[2345] respawn instance /dev/ttyS0 exec /sbin/mingetty /dev/ttyS0
Add "ttyS0" to /etc/securetty And then run:
initctl start ttyS0
