Xen users - Jan 2012 - CentOS 6.2 XEN 4.1.2 Serial console

Hey,

I''m more a reader than a poster on this list but Recently I installed
CentOS 6.2 with myoung XEN Dom0 kernel and 4.1.2 hypervisor, at first
everything went smooth, DomUs run like a charm and so on, but my serial
console is gone for good tried dmesg | grep tty which spits out:

uname -r
2.6.32-131.21.1.el6.xendom0.x86_64

dmesg | grep tty

console [tty0] enabled

Weirdest thing when I remove the kernel /xen.gz ...... line from grub.conf
it shows the port IO, IRQ and so on.

my grub.conf reads

title   XEN dom0
root    (hd0,0)
kernel  /xen.gz loglvl=all guest_loglvl=all dom0_max_vcpus=1 dom0_vcpus_pin
conswitch=g com1=115200,8n1 console=vga,com1 dom0_mem=384M
module  /vmlinuz-2.6.32-131.21.1.el6.xendom0.x86_64 ro
root=/dev/mapper/xaero-root nomodeset rd_NO_LUKS LANG=en_US.UTF-8
rd_LVM_LV=xaero/swap rd_LVM_LV=xaero/root  KEYBOARDTYPE=pc KEYTABLE=es
rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto rd_NO_DM
module  /initramfs-2.6.32-131.21.1.el6.xendom0.x86_64.img

As you see line is there, but when I run either minicom or screen
/dev/ttyS0 115000 they error out. Is there something I''m missing out
here

I''ve gone through many many xen-list archives and google searches and
can''t
find a solution for my issue.

Your advise would be thanked for ever.

I do not know how much it will help the problem, I would have done the 
following way:
will become a cheap video card pci, and would use it, I actually do.
Alternatively use the KVM, or video card vivo or HP server iLo
