Problem with finding kickstart file from the cdrom

[Oguz Yilmaz]

Hello,

I was using a kickstart distro with kernel 2.6.18. Recently I have decided
to change this distro cd to use kernel 3.4.52. I have prepared all new rpm
files and produced iso.

I am testing the iso file on proxmox environment with qemu. With tha same
guest vm the oldu distro succfully boots and find kickstart file and
installs. With the new iso I have problems.

"unable to find the kickstart file...."
cdrom:/isolinux/ssd.cfg

In tty3 I can follow:
[    1.620980] sd 0:0:0:0: Attached scsi generic sg0 type 0
[    1.621253] sd 0:0:0:0: [sda] 33554432 512-byte logical blocks: (17.1

[    1.636220] cdrom: Uniform CD-ROM driver Revision: 3.20

When I add loglovel-debug in to anaconda boot cmdline I can see error log.

ERROR: No CDROM devices found!


I have also checked the previous iso file. It was correctly recognizing
cdrom as hdb while problematic new kernel iso recognizes it as sr0 device.

hdb: QEMU DVD-ROM, ATAPI CD/DVD-ROM drive

ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

mntloop loop0 on /mnt/runtime as ....

got url from cdrom://hdb:/mnt/source


If I write ks url as "hd:scd0:/isolinux/ssd.cfg" then anaconda mounts and
reads the ks file.


getting kickstart file from harddrive

Loading ks from device scd0 on path /isolinux/ssd.cfg

...

file copied to /tmp/ks.cfg


However ks.cfg includes "install" and "cdrom" lines. Then it againg tries
to find Cdrom and gives error.


This problem occurs in stage1 and this stage does not enable tty2 debug
shell and sshd options. So I have limited debug options.


Anaconda version is 11.1.2.168 , kernel version 3.4.52.


What do you suggest on the problem?
