Bug ID: 1198643
           Summary: Append parameters to grub.cfg
           Product: Fedora Documentation
           Version: devel
         Component: virtualization-guide

Description of problem: The instructions[1] of how to append parameters to
Grub's grub.config file is obsolete on recent releases of Fedora. The file
/boot/grub/grub.conf doesn't exist anymore.

The way to do it now is (tested on Fedora 20):
1 - Edit /etc/default/grub
2 - Append information at the line GRUBCMDLINELINUX=" ... console=tty0
console=ttyS0,115200 ... ")
3 - Regenerate the /boot/grub2/grub.cfg file with the command "grub2-mkconfig
-o /boot/grub2/grub.cfg"

Additional info: The documentation is refered to version 18 where it should
work, but as we don't have a documentation in a most atual release of Fedora
for that subject, you can write a note for the users of most recent releases of
Fedora that came with Grub2, where the procedure is according with that listed
above.
