Xen devel - Jan 2005 - serial console with xen

Hi,
i''ve tried to activate serial output with the hypervisor and dom0 but 
with no success
I''m just able to have serial console for grub with those two following 
line (so with this i''m sure that my serial configuration is oK)
serial --unit=0 --speed=57600
terminal --timeout=10 serial console
and with this configuration (but i tried some others) i can''t have xen 
hypervisor output on serial line.
Can someone give me some clues ?


#####My grug configuration##########
title  XEN linux root: /dev/hde2 low ram
kernel (hd0,1)/boot/xen.gz com1=57600 dom0_mem=32768
module (hd0,1)/boot/vmlinuz-2.4.27-xen0 root=/dev/hde2 ro console=tty0 
xencons=tty

I expect from this setup to have also my dom0 console on serial line, a 
couple of month ago i''ve read a message from Ian (i think) saying that 
it''s not necessary to supply console=tty0,ttyS0 in order to have dom0 
console on the serial line
As i''ve understood, suppling tty0 to the "console" parameter
will tell
the dom0 kernel to use the same console as the xen hypervisor.

Am i wrong ?

Is there a more complete documentation about console configuration than 
the xen 2.0 user manual ?

Regards
Matthieu

I''m using

serial --unit=0 --speed=115200
terminal serial

title Xen 2.0 / XenLinux 2.6.9
kernel (hd0,0)/xen.gz dom0_mem=65536 com1=115200,8n1
module (hd0,0)/vmlinuz-2.6.9-xen0 root=/dev/hda3 ro console=ttyS0
#ttyS0 is actually Xen''s fake

Don''t compile anything serial-related into your kernels.
