I'm facing some problem when I'm trying to work with serial console with Xen. I followed the instructions from user manual
(http:www.cl.cam.ac.uk/Research/SRG/netos/xen/readmes/user/user.html ) and constructed the grub.conf accordingly. I'm attaching the grub.conf file  here and would be referring to it in the next few lines. The problems faced are as follows:

1. I can boot normal Linux FC4 kernel and direct its output to serial console (and see the messages in a separate monitor) using the options as mentioned in the grub.conf.
    If I do the exactly the same (meaning, whatever you can see as uncommeted lines in the xen-related portion of the grub.conf),
    I can't see the messages in the separate monitor.

2. If I uncomment the third line in the following:
title Fedora Core (Mar 17-xen0)
        root (hd0,0)
#       kernel /xen.gz dom0_mem=131072 com1=9600,8n1
        kernel /xen.gz dom0_mem=131072
        module /vmlinuz- ro root=LABEL=/ rhgb quiet console=tty0 console=ttyS0,9600n8
        module /initrd-

then Xen even does not boot up. I'm not sure if I put the correct entry in the third line, though.

Can anyone kindly point out my mistake or tell me if I'm missing something? I wanted to see the messages in the different monitor (conmnected via serial console) for the purpose of debugging. Hence, it'd be nice if someone can let me know easier way of debugging Xen kernel code.

Thanks  in advance,
