Public bug reported:
DISTRIB_DESCRIPTION="Ubuntu 22.04.5 LTS"
apt-cache policy cloud-init
cloud-init:
Installed: 25.1.2-0ubuntu0~22.04.1
Candidate: 25.1.2-0ubuntu0~22.04.1
Version table:
*** 25.1.2-0ubuntu0~22.04.1 100
100 /var/lib/dpkg/status
At some point after June 4th 2025 our Octavia OpenStack test jobs
started to fail.
On closer inspection we found that the VMs were not getting IP addresses
configured.
I was able to reproduce this on a local devstack system.
On the failing VM I connected to the console locally. The cloud-init
configuration appears correct and the config drive mounted with the
correct information.
What is odd however is there are no cloud-init logs in /var/log.
It appears as if it didn't run on boot.
I compared our images from the last known successful test run and the
current image and the only package I see different is:
< cloud-init all 24.4.1-0ubuntu0~22.04.2 [566 kB]
---
> cloud-init all 25.1.2-0ubuntu0~22.04.1 [568 kB]
I then made a copy of the image and replaced 25.1.2 with the 24.4.1
version and this image booted as expected.
This issue is 100% repeatable with 25.1.2.
If you would like to create an image we have tools available to create one that
reproduces the problem:
1. git clone https://opendev.org/openstack/octavia
2. cd octavia/diskimage-create
3. run "./diskimage-create.sh -r <root password> -d jammy"
4. It will create a qcow2 image that boots under OpenStack with config drive
