QA - coordination #123800: [epic] Provide SUSE QE Tools services running in PRG2 aka. Prg CoLo
Setup a modern UEFI httpboot setup on o3 with dnsmasq size:M
0%
Description
Motivation¶
Modern machines use UEFI and support httpboot. Some machines don't even support old legacy boot, in particular when there are NVMe devices. Eng-Infra is already using a new way in particular in PRG2 so we should use something like that for our own setup as well, e.g. follow https://documentation.suse.com/sles/15-SP5/html/SLES-all/cha-deployment-prep-uefi-httpboot.html
Acceptance criteria¶
- AC1: physical PRG2 o3 workers can start an autoyast based installation
Suggestions¶
- The referenced SLE doc use dnsmasq as example so that should be simple enough for us to follow.
- Read in #132143-30 what mcaj did but with dhcpd so we have it easier with dnsmasq anyway
- Use qemu to test the setup first. Validate with physical machines later
- Look into o3:/etc/dnsmasq.d/openqa.conf for likely all relevant settings
- See https://progress.opensuse.org/projects/openqav3/wiki/#UEFI-boot-via-iPXE

- Target version changed from future to Ready
- Parent task set to #123800
It seems we need this urgently as the new machines in PRG2 with the NVMe devices don't support legacy PXE boot. Please follow https://documentation.suse.com/sles/15-SP5/html/SLES-all/cha-deployment-prep-uefi-httpboot.html and/or ask mcaj for help.

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.
#!ipxe
dhcp
# Global variables used by all other iPXE scripts
chain --autofree tftp://192.168.112.100/ipxe/boot.ipxe.cfg ||

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 ||

- 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.
