Manually editing may not be a good idea:

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub2-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#

I can confirm that I can change the default entry for grub2 on F20 to Xen:

I use a script I wrote which you can download at
https://github.com/zma/usefulscripts/blob/master/script/grub2-select.bash
which summarize the steps from
http://www.fclose.com/3826/setting-default-entry-in-grub2-and-grub/ .

I just tried and unfortunately Xen can not boot either for me ;( It
got stuck. I made a video recording it:
http://file.pkill.info/file/f12-xen-fail-to-boot.mov (25MB). It worked
well for me last time I tried it on F19. No idea what is wrong.

The versions of Xen and Kernel:

xen-4.3.2-2.fc20.x86_64
kernel-3.13.10-200.fc20.x86_64

Best,
Eric
