Dear Pasi,
Thanks for your help! It works!
I wonder why this didn't work:
title Fedora (2.6.31-rc6-enming.teo) Serial Console
root (hd0,0)
kernel /xen.gz iommu=1 com1=115200,8n1 console=com1
module /vmlinuz-2.6.31-rc6-enming.teo ro
root=/dev/mapper/vg_fedora11_host-lv_root selinux=0 console=ttyS0,115200
module /initrd-2.6.31-rc6-enming.teo.img
And this worked:
title pv_ops dom0-test (2.6.29-rc7-tip) with serial console
root (hd0,0)
kernel /xen-3.3.gz dom0_mem=1024M loglvl=all guest_loglvl=all
com1=19200,8n1 console=com1
module /vmlinuz-2.6.29-rc7-tip ro root=/dev/vg00/lv01 console=hvc0
earlyprintk=xen
module /initrd-2.6.29-rc7-tip.img
Anyway, I still got a tty1 output! I thought that after using serial console,
it is not supposed to output to a monitor anymore?
As a result of this, I still can't hide the VGA card from dom 0 and pass it
through to the Windows Dom U.
Any ideas?

Hi All,
I have tried to configure serial console for Xen hypervisor, dom 0
kernel and Linux login but it does not seem to be working.
Here is my grub configuration for serial console:
title Fedora (2.6.31-rc6-enming.teo) Serial Console
root (hd0,0)
kernel /xen.gz iommu=1 com1=115200,8n1 console=com1
module /vmlinuz-2.6.31-rc6-enming.teo ro
root=/dev/mapper/vg_fedora11_host-lv_root selinux=0 console=ttyS0,115200
module /initrd-2.6.31-rc6-enming.teo.img
http://wiki.xensource.com/xenwiki/XenParavirtOps
paste from that page:
Working example grub.conf with serial console output:
title pv_ops dom0-test (2.6.29-rc7-tip) with serial console
root (hd0,0)
kernel /xen-3.3.gz dom0_mem=1024M loglvl=all guest_loglvl=all
com1=19200,8n1 console=com1
module /vmlinuz-2.6.29-rc7-tip ro root=/dev/vg00/lv01 console=hvc0
earlyprintk=xen
module /initrd-2.6.29-rc7-tip.img
Is the above configuration correct? On my Intel Desktop Board DQ45CB, I
have a COM1 header on the PCB and I have connected an external serial
port to this header and also enabled COM1 in the BIOS.
After selecting the above entry in GRUB still on VGA, a cursor at the
top left corner of the monitor shows up, which means Xen and Dom 0
kernel are booting up on the serial console and not on VGA.
However, after some time, a login prompt finally displays on my VGA
monitor! Isn't it NOT supposed to show up on VGA and should show up in
serial console instead?
You also need to have the gettys configured properly.
