Description erik nguyen 2004-11-17 20:02:39 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20030925

Description of problem:
After network installation, the installer should create the serial
terminal entries (extracted from the pxelinux.cfg/default file) and
appending them to the kernel boot line in /boot/grub/grub.conf i.e.,
adding "console=ttyS1,9600". If this is not accomplished then the
system after reboot will hang indefinitely in a blank window of the
serial console or will not display any boot messages to the serial
console until the login prompt appear by running /sbin/agetty in

The default entry I used:

label lr4b2
  kernel r4b2/images/pxeboot/vmlinuz
  append acpi=off ksdevice=eth0 console=ttyS1,9600n8 load_ramdisk=1
network ks=nfs:

The ks1.cfg I used:

langsupport en_US
lang en_US
keyboard us
mouse generic3ps/2 --device psaux
timezone --utc America/Los_Angeles
rootpw abc123
zerombr yes
bootloader --location=mbr
nfs --server --dir /home/pxeboot/sqa/r4b2
clearpart --linux
part /boot --fstype ext3 --size 64
part  swap --size 1024
part / --fstype ext3 --size 1 --grow
network --bootproto dhcp --device eth0
auth --useshadow --enablemd5
firewall --disabled
@ Everything

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. proceed to do a pxe-install using provided 'default' entry and
ks1.cfg file.

2. after installation, system will reboot

3. telnet to the serial terminal: either nothing will be displayed or
no boot messages will be displayed until the login prompt appear.

Actual Results:  no display of serial console outputs

Expected Results:  display of serial console outputs

Additional info:

The workaround is to boot the system in rescue mode then chroot
/mnt/sysimage, then edit the /boot/grub/grub.conf file to add
"console=ttyS1,9600" to the kernel boot line.

adding 'serial' to the /pxeboot.cfg/default file solved the problem !

label lr4b2
  kernel r4b2/images/pxeboot/vmlinuz
  append acpi=off ksdevice=eth0 serial console=ttyS1,9600n8 ...
