Serial[edit | edit source]
To enable serial output, edit /etc/default/grub with the following lines:
GRUB_TERMINAL_OUTPUT="console serial"
GRUB_CMDLINE_LINUX="rhgb console=ttyS0,115200n8 "
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200"
Then update the grub config:
# grub2-mkconfig -o /boot/grub2/grub.cfg
