I have two computers: one is the server I installed and the other is my macbook on which I run a virtual machine (using VMWare fusion) that does the net boot. I have additional VM on it with ubuntu 10.4 installed on it for other tests. The server runs ubuntu 10.4 server and the client image for network boot is ubuntu 10.4 desktop that I previously prepared as explained in the link above on a VM on my laptop.
The problem is that after loading the kernel and initrd (and outputting many things that I can't read because it happens too fast) I get the following error:
At first I thought it means that the NFS is not accessible but I was able to mount it and access its files from the other VM so it is not the problem.
I have no idea what this error practically means, I saw in some google hits that it means that the network driver is missing. However, I created the initrd file on the same VM that now tries to boot and as explained in the tutorial. I tried both ways (mkinitramfs and update-initramfs) with no success.

I've set up a PXE boot server and I'm having a slight snag in the booting process. On the client machine, DHCP renders fine and TFTP seems to begin but then the system hangs.

Hi Experts,
I am doing PXE boot for my GNU/Linux device and pxelinux.0 loads the kernel as well as initrd images I have mentioned in the config file but it looks like it is not considering the init= option. Instead it starts the default INIT program.

I have been asked to modify our PXE server such that there will be only one entry in the pxelinux.cfg/default file, where the same kernel and initrd.img will be used regardless of what operating system is to be installed, and the user will type in the path to the kickstart file that will be used. ...

INITRAMFS.CONF(5) initramfs.conf manual INITRAMFS.CONF(5)NAME
initramfs.conf - configuration file for mkinitramfs
DESCRIPTION
The behaviour of mkinitramfs can be modified by its configuration file.
Each line in the file can be a configuration variable, a blank line, or a comment. The value of an variable is assigned by an statement of
the form: name=[value]
Configuration options can be broken out into configuration snippets and placed in individual files in the /etc/mkinitramfs/conf.d direc-
tory. Files in this directory are always read after the main configuration file, so you can override the settings in the main config file
without editing it directly.
GENERAL VARIABLES
MODULES
Specifies the modules for the initramfs image.
Modules listed in /etc/initramfs-tools/modules and /usr/share/initramfs-tools/modules.d/* are always included in the initramfs, and
are loaded early in the boot process.
list doesn't load any additional modules at boot time, other than those listed in the above files.
most adds most file system, all ata, sata, scsi and usb drivers.
dep tries to guess which modules are necessary for the running box and only adds those modules.
netboot adds the base and network modules, but skips block devices.
The default setting is most.
BUSYBOX
Include busybox utilities for the boot scripts. If set to 'n' mkinitramfs will build an initramfs without busybox. Beware that
many boot scripts need busybox utilities.
COMPRESS
Specifies the compression method used for the initramfs image. mkinitramfs will default to gzip if the kernel lacks support (CON-
FIG_RD) or the corresponding userspace utility is not present.
UMASK Set the umask value of the generated initramfs file. Useful to not disclose eventual keys.
COMPCACHE_SIZE
Amount of RAM to use for RAM-based compressed swap space. The default is not to use compcache.
An empty value - compcache isn't used, or added to the initramfs at all.
An integer and K (e.g. 65536 K) - use a number of kilobytes.
An integer and M (e.g. 256 M) - use a number of megabytes.
An integer and G (e.g. 1 G) - use a number of gigabytes.
An integer and % (e.g. 50 %) - use a percentage of the amount of RAM.
You can optionally install the compcache package to configure this setting via debconf and have userspace scripts to load and unload
compcache.
NFS VARIABLES
BOOT Allows one to use an nfs drive as the root of the drive. The default is to boot from local media (hard drive, USB stick). Set to
nfs for an NFS root share.
DEVICE
Specifies the network interface, like eth0.
ROOT Allows optional root bootarg hardcoding, when no root bootarg can be passed. A root bootarg overrides that special setting.
NFSROOT
Defaults to auto in order to pick up value from DHCP server. Otherwise you need to specify HOST:MOUNT.
