Hi Tony,
There is a bug about this
issue. Please have a look at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180126
If want to use serial
port input, I have to disable SMP. Following is a workable grub config to
enable serial out input, but the kernel will be UP. I am not sure if there is
any better solution.
title Fedora Core 5
root (hd0,0)
kernel
/boot/xen.gz-xxx_FC5 dom0_mem=262144 com0=115200,8n1
apci=off
module
/boot/vmlinuz-xxx_FC5hypervisor ro root=/dev/sda1
console=ttyS0
console=tty0 pci=noapci
module
/boot/initrd-xxx_FC5hypervisor.img
Best Regards,
Yongkang (Kangkang) ÓÀ¿µ

Subject: [Fedora-xen] FC5 - serial
console - no characters received by host?
Hi there,
I've been working with the FC5 Xen stuff for the past
few weeks after trawling many options for building a redundant server farm;
It's a great build and congratulations to all who put this together.
I have a little issue with my serial console which is
putting hte brakes on deployment though: I want to use the serial console on
com2 (the default on the Intel mainboard I use) to give me the grub console,
Xen console and Linux consoles. I've had this working fine on previous
releases from SuSE and others and on the current hardware.
When happens at the moment is that the machine boots,
gives me the grub menu, where I can choose my boot system (so it's hearing my
keystrokes) but once it proceeds into the Xen and ultimately Linux, it doesn't
want to hear keystrokes from me any more: I can't CTRL-A (x3) and get the Xen
console, nor the linux console which is configured in /etc/inittab. I see
the boot messages go past and get a login prompt, but no keystrokes get through
or can control the machine.
It's making it tricky to send the box to co-lo as I
can't get serial control if I take down the network, or Hypervisor control to
reboot Dom0.
My rpms are:
kernel-xen0-2.6.16-1.2080_FC5
xen-3.0.1-4
and my grub.conf is:
default=0
timeout=5
#splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu
#
serial --unit=1 --speed=9600 --word=8 --parity=no
--stop=1
terminal --timeout=10 serial console
#
title Fedora Core (2.6.16-1.2080_FC5xen0)
root (hd0,0)
kernel
/xen.gz-2.6.16-1.2080_FC5 dom0_mem=384000 com2=9600,8n1 console=com2,vga
sync_console
module
/vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/VolGroup00/LogVol00 rhgb selinux=0
module
/initrd-2.6.16-1.2080_FC5xen0.img
I'd appreciate any guidance on silly things I may have
done here; I'm banging my head on this one.
Many thanks,
Tony
