Do you also have a line in grub.conf of the form
serial --unit=0 --speed=115200
terminal --timeout=10 serial console
I don't have xen 4.0.1 myself and so can't test it with that,
but this functionality is part of grub and shouldn't matter
whether you are using Xen or not. At this state you have not
loaded anything that is xen-dependent.

Xen-users,
I am having trouble getting to the grub boot menu, via a serial console. The serial
console is working and even gives me "Press any key to continue." many times
very nicely, but when I press the any key, I get no menu and grub eventually times out
and boots the default hypervisor. I am using
terminal --timeout=10 console serial
on a machine that has a serial port, using a null modem cable.
The menu works fine over the directly connected keyboard and monitor, so I am
sure it is not a broken menu per se.
I have tried lots of combinations of grub set up, all with the same results or worse, e.g with and without
"sync_console", putting "serial" before "console", leaving either "console" or
"serial" out. I also tried a number of different line speeds from 115200 all the way down to 9600, but nothing seems to
make a difference. I could not find anything in the Xen wiki about grub menu over serial, and nothing googled either.
Before I try any more, does anyone know if the grub menu is even supposed to
work over serial, for Xen 4.0.1?
Sincerely,
John
