Description Stephen Benjamin 2020-05-01 14:24:27 UTC
+++ This bug was initially created as a clone of Bug #1830161 +++

Description of problem:

When booting via UEFI, using IPv4 PXE protocol, error of no network devices shows up. Via https://github.com/openshift/ironic-image/blob/master/dnsmasq.conf.j2#L28 we see that ipxe.efi is set but it should be using snponly.efi https://github.com/metal3-io/ironic-image/blob/master/dnsmasq.conf.j2#L41

Steps to Reproduce:
1. Ensure UEFI+ IPv4 PXE protocol in UEFI settings
2. Attempt an IPI on BM install

Actual results:
Fails to PXE masters with No network devices

Expected results:
Properly PXE the master nodes. 


--- Additional comment from Julia Kreger on 2020-05-01 00:13:14 UTC ---

UEFI stacks are supposed to supply network stacks to the firmware images loaded such as those for ipxe before the operating system loads. This means we should be using the snponly.efi binary for uefi with IPv4. With IPv6, the file is already correct.

Pull requests created for openshift and metal3.

We can see that snponly.efi is loaded on IPv4 provisioning network with 4.4.5 image.
