[Xen-users] CentOS 6.2 XEN 4.1.2 Serial console

[David Gonzalez <dgonzalezh@xxxxxxxxx>]

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.
