hi,

I have tried this for several times with different configuration on
xen-unstable branch (rev. 17773).

The following is my grub.conf file.

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
title Xen 3.3 serial console (unstable)
    root (hd0,0)
    kernel /xen-3.3.gz com1=115200,8n1 console=com1,vga sync_console
    module /vmlinuz-2.6.18.8-xen ro console=tty console=ttyS0,115200n8
    module /initrd-2.6.18.8-xen.img

With this configuration, I can get a login prompt when Dom0 finishes
booting. I think it is because the following command in /etc/inittab.

s0:2345:respawn:/sbin/agetty -L 115200 ttyS0 vt100 // At least it
verifies that the serial port/cable is working fine.

If I put the xencons=ttyS0 onto the command line, I even can't get a
login prompt when Dom0 is up.

Any suggestions? This is on x86_64 machine.

Thanks,
Neo
