Linux ltsp client failing to boot. After ubuntu splash screen, it dumps me to busybox
 
Hello everyone,
I have installed ubuntu ltsp from ubuntu 12.04 alternate cd in VMware workstation 10. The client is also a VM for testing purposes. The server has 2 nics. DHCP and Network interface for eth0 are properly configured. The client even picks up the ip from the dhcp pool and boots upto a point. After Ubuntu splash screen, this is what i get.
Code:

Trying to load: pxelinux.cfg/default    ok
mount: mounting /dev/nbd0 on /root failed: Input/output error
/scripts/init-bottom/ltsp: line 27: panic: not found
chroot: can't execute '/usr/bin/test': No such file or directory
mount: mounting /root on /rofs failed: Invalid arguement
mount: mounting /rofs on /root/dev failed: No such file or directory
mount: mounting /dev on /root/dev failed
.
.
.
.
.
Target filesystem doesn't have requested /sbin/init-ltsp
No init found. Try passing init= bootarg

(initramfs)_

I have googled a lot and found this as one of the most common issues. Being a newbie I am not able to resolve this issue as per "one or two" successful resolutions on the web. Kindly help me on this. Thanks!

You HAVE INSTALLED, or you are TRYING TO INSTALL via PXE boot??? Based on what you posted, it's not clear. Also, you don't say what the "one or two" things you've tried are, or what the results were. And what guide are you following to get this to work? And why are you loading 12.04 LTS, when the latest is 14.04?? And after two years, 'newbie' isn't accurate.

@TBone
I have followed a tutorial from ubuntu forums. I have already installed. The client is also booting successfully from the image generated by the ltsp server. After ubuntu splash screen, I get that error. Its like a shell prompt where everything works but a login screen is expected. I've seen some successful tutorials on 12.04 thats why i didn't go for 14.04.

And AGAIN...you don't tell us WHAT guide you followed.

Doesn't look like it, since the very first line of your output says you're loading the pxelinux config, which is what you do when you're doing the install...after that', it's INSTALLED, and runs off your hard drive.

Again, 12.04 is OLD...use the latest versions of things, and your problem may go away. Since this is a new installation, and it already doesn't work, you certainly won't lose anything by upgrading.

Again, unless you tell us what you've done/followed, we can't guess as to why things are failing. You still haven't answered the questions from the first post either.

@TBone,
"Its already installed" I meant the ltsp server is installed as I've mentioned. What I was trying to install was the client. And 14.04 doesn't provide alternate-iso. The couldn't get the download file which is the reason i went for 12.04. Anyway, this problem is solved too because i switched to Vsphere from workstation. As the virtual switch is already configured, the clients booted up with no problem. I need to get my dhcp configuration concepts clear. I think that was the reason the boot process on clients was failing in VMware workstation

Right...which brings us right back to "it IS installed, or you're TRYING to install"...and the answer is now revealed to be you're TRYING to install it via PXE boot.

No idea what you mean here. There are many 'alternate' images on the Ubuntu site, for different architectures, different install methods, etc. Not hard to find.

Glad it's working, but you're wrong...there is NO reason to use 12.04 for a new installation.
