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.
Your diskless machine is not getting an IP address:
So yes, network problems for one reason or another.
The call trace is probably irrelevant. What happens is that 'init' is unable to grab an IP address, gives up and quits, which causes a kernel panic since init should never ever quit.
But it should already have an IP address - it gets it during boot from DHCP....
(I see that happening at the beginning of boot - it gets the IP I assigned to its MAC address)
The configuration in the nfsroot only matters once you already have network. If it's never connecting to NFS, this is happening before it. I wonder if the kernel has kernel-level autoconfiguration done -- meaning it will attempt to get DHCP by itself. Or if IP-Config is a proprietary ubuntu program, you will need to ask them.
thanks, I posted a specific question on that in their forum
however, I have the same main question posted there from hours ago and nobody answers... I'll have to wait patiently...

Maybe it is related to the NFS?
Before the error message I see info on that but I don't really know how to read it:
Then after a minute:
Hope it helps...
Thanks!
