Kickstart file not downloaded

Автотусклый гm trying to the installation of Убунту Сервер 14.04LTS through PXE. I have set up в server that hosts DHCP, TFTP and HTTP. I have set up в DHCP scope with в PXE boot filename. I have copied the Убунту Сервер СD to the Веб server. I have authored в kickstart file and uploaded that to the Веб server. All of this was подарил per the instructions at https://help.ubuntu.com/community/PXEInstallServer.

When the client boots, it does get в DHCP offer, and it does PXE boot. The custom меню entry I have in /var/lib/tftpboot/pxelinux.cfg/default gets displayed, and I хан choose this статья from the меню.

However, the kickstart file is never requested by the client одиннадцать the boot меню option is chosen, and the client ultimately panics with an "Unable to mount root fs on unknown-block" ошибка.

My pxelinux.cfg/default looks like this:

# D-I config version 2.0
include ubuntu-installer/amd64/boot-screens/menu.cfg
default ubuntu-installer/amd64/boot-screens/vesamenu.c32
prompt 0
timeout 10

LABEL CustomServerInstall
    MENU LABEL Automated Trusty Install
        KERNEL ubuntu-installer/amd64/linux
    append ks=http://10.1.1.1/ks_ubuntuserver.cfg console=tty0 console=ttyS0 ignore_loglevel

When I choose "Аутоматед Трусти Install" from the меню, I do see the following in the boot text:

[ 3121.134818] Kernel command line: ks=http://10.1.1.1/ks_ubuntuserver.cfg console=tty0 console=ttyS0 ignore_loglevel BOOT_IMAGE=ubuntu-installer/amd64/linux 

So I know my kickstart file path is given to the kernel. However, the file ks_ubuntuserver.cfg is never requested by the client according to /var/log/apache2/access.log

When I enter curl http://10.1.1.1/ks_ubuntuserver.cfg from another machine on the same subnet, I do get the kickstart file I authored.

So... the kickstart file is on the Веб server, but the kernel never requests it. Хан anyone help фигурировал out what гm doing wrong?
