hello,
I am using fedora core 6.
and there is Xen Virtual Console installed in my system ....due to which I am not able to use my serial ports.......
What is thi Xen virtual console and what it does?????

So, Can I unintall this Xen virtual Console.....
or any method so that I can use my serail port...

thanks

From the Fedora 6 Xen Quickstart docs:

You need to set up the Xen host for serial console output, and set up a remote host to capture it. For the console output, you need to set appropriate options in /etc/grub.conf, for example:

title Fedora Core (2.6.17-1.2600.fc6xen)
root (hd0,2)
kernel /xen.gz-2.6.17-1.2600.fc6 com1=38400,8n1 sync_console
module /vmlinuz-2.6.17-1.2600.fc6xen ro root=LABEL=/ rhgb quiet console=ttyS0 console=tty pnpacpi=off
module /initrd-2.6.17-1.2600.fc6xen.img

for a 38400-bps serial console on com1 (ie. /dev/ttyS0 on Linux.) The "sync_console" works around a problem that can cause hangs with asynchronous hypervisor console output, and the "pnpacpi=off" works around a problem that breaks input on serial console. "console=ttyS0 console=tty" means that kernel errors get logged both on the normal VGA console and on serial console. Once that is done, you can install and set up ttywatch (from fedora-extras) to capture the information on a remote host connected by a standard null-modem cable. For example, on the remote

for a 38400-bps serial console on com1 (ie. /dev/ttyS0 on Linux.)
As you stated in reply.....but my serial port is 16550 UART........
then also I have to make these changes only.....

Check for it also:::::::::::::::::::

title Fedora Core NEW (2.6.18-1.2798.fc6xen)
root (hd0,0)
kernel /xen.gz-2.6.18-1.2798.fc6
module /vmlinuz-2.6.18-1.2798.fc6xen ro root=LABEL=/ xencons=xvcX
module /initrd-2.6.18-1.2798.fc6xen.img

this is the copy that I had made to my grub.conf.........
Is this also a solution?????
but when I boot my system than It shows too many failures with booting .....
(different - diffrent modules failed at start up)

Also tell me What ever modifications you told me I should make their individual Entry or just edit to my earlier grub.conf
