no such network device in the iPXE boot

[gfhoffmann]

Hey guys! I'm having the problem below:

It seems that iPXE is not finding my network interface, even when it exists on my machine.

How can I solve this problem?

Thanks!

You seem to be using a embedded script pointing to net1, the second interface.
Without posting the script you are using we don't know what you are trying to do.

It might be as simple as you should not use any embedded script.
Otherwise add ifstat to the start of your embedded script and post the output.

So you have no NICs in the machine (that iPXE can find)
Most likely no native drivers in iPXE for NICs in the machine.
But we can't help more here without more info.

You are using iPXE in a somewhat advanced way without knowing much about iPXE at all. You might have to do quite s bit of explaining here to get good help.

I'm waiting my colleague to pair with me to try to give you more info about.
I'm not the expert in the iPXE feature, just trying my best.
Sorry if I was not able to give all the information right away.
But I will return with more info to try to understand this problem.
And thanks for your support so far, its really helping a lot.

Hey there! I'm back with some infos.

Which NIC is in the machine? Do you have a pciid? (Use lspci -nn in Linux)

c8:00.0 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller [14e4:16d8] (rev 01)
c8:00.1 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller [14e4:16d8] (rev 01)

Where does pxelinux come from in this boot sequence?

In our runtime we get the ipxe code from github, configure everything, run a make using an EMBED ipxe script that we created to configure the interfaces with proper IPs and chain to other ipxe script.

Just to give some context, we have other 2 machines with the same NIC and everything worked, and in other 2 machines it didn't.

Going back then. The screenshot is from a bios booted machine which starts pxelinux, which boots local disk, which then starts iPXE? Why are you not pxebooting into iPXE directly? You should then be able to use undionly.kpxe.

Another thing about net numbers. you should never assume which number a specific nic has. This could change.

Hi there! So, I guess this was the best scenario for our specific use case.
About the net numbers, in the runtime, before booting iPXE, we access the machine and get the updated numbers to get the right one.
