TFTP Access Violation

[John Griebel]

Hi everyone, the top thread her right now is having a similar but I think different problem. Hopefully this thread isn’t redundant. I’m trying to set up something similar to this guide, but in two VMs: [url]http://www.howtogeek.com/57601/what-is-network-booting-pxe-and-how-can-you-use-it/[/url]. So I installed Fog 0.32 on Ubuntu Server 12.04 LTS using the instructions in that guide. The installation goes smoothly and everything, but when I boot the PXE client VM, it gives the following error:

PXE-T02: Option negotiation failure (file not found or inaccessible?)
PXE-E3C: TFTP Error - Access Violation
PXE-M0F: Exiting Intel PXE ROM.

I have found some things that say I need to change some permissions but I can’t understand for sure what files need to be changed, or if that is even the case. If I need to post more information (I’m sure I left some things out), I’ll be more than happy too. Also, just to be clear, I haven’t gone any further in the guide I posted above than installing FOG and trying to test it. I’ve gotten this setup to work before on physical machines, so it has to be something with the VirtualBox settings, right?

I had the same problem just now.
The solution is to connect the host to the correct network.
