Kernel panic - not syncing: VFS

[george1421]

@cleric.marcos You might have an older version of dnsmasq on your system than I think.

Lets try this. Change this line

pxe-service=X86PC, "Boot from network", undionly.kpxe

to

pxe-service=X86PC, "Boot from network", undionly

The version of dnsmasq you have may not like the extension on the boot from menu

Then you need to create a new symbolic link:
ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0

From your picture you can see its launching the section:
pxe-service=X86PC, "Boot from network"

because its printing “Boot from network” on the screen. I’m guessing it didn’t like the .kpxe as part of the boot file.

If this doesn’t work we’re going to need to get a pcap of the dhcp process to understand what dnsmasq is sending to the target computer.

@george1421 My mind is still blown concerning why anyone would have made dnsmasq add stuff to filenames. I’m so so glad that’s fixed now.

@Wayne-Workman I believe they were trying to follow “best practices” and/or “standards”.

When DNSMasq started to come into existence, I believe the norm was to boot to a “.0” labelled file. So to lessen typing, you could just request pxelinux instead of the whole pxelinux.0 bit of it. (Pxelinux was pretty much the norm at this point I would say.) Of course as more modern nbp systems came out this didn’t hold any more value for reasons we all know too well now.

@george1421 and @Tom-Elliott Thank you SO much!
After some test, I discover the issue.
I install fog in a desktop, rename the undionly.kpxe, make the soft link, and enable the tftp service on dnsmasq, and it worked!!!
I documented everything, and made ir again on virtualbox, and it worked, so the problem was me, hehe.
Thank you very much for all the help and patience. I’am working in cibersecurity, and Iam also in charge of the workstation here, so FOG really help me out.
Thanks again to both of you.
If I find a bug o security issue I will notify it.

See ya!

@cleric.marcos You’re more than welcome. I do want to say I did very little to help anything here. I think @george1421 deserves more of the kudo’s here than I do.
