The ipxe/ipxe.pxe file contains an embedded script that I was able to extract by doing a virsh dump --memory-only myvm /tmp/f.img on a vm that loaded that file and running strings on the memory dump.

- Description updated (diff)
Improved embedded script that uses next-server and no hardcoded IP address:
#!ipxe
dhcp
# Global variables used by all other iPXE scripts
chain --autofree tftp://${next-server}/ipxe/boot.ipxe.cfg ||
# Boot <boot-url>/menu.ipxe script if all other options have been exhausted
chain --replace --autofree tftp://${next-server}/ipxe/menu.ipxe ||

How to build pxe and efi iPXE bootloader:

- Status changed from In Progress to Feedback
Updated dnsmasq and nginx config on o3.
Updated tftpboot root on o3.
Pushed files to scripts repo: https://github.com/os-autoinst/scripts/pull/251
Tested that UEFI-tftp, UEFI-http and BIOS-tftp work in o3 network, using VMs on a worker host.
- Status changed from Feedback to Resolved
PR merged and tests done with BIOS-tftpboot, UEFI-httpboot and UEFI-tftpboot via vm and the UEFI tests also via hw (openqaworker28) on o3.
Installing openqaworker28 worked fine.
