I think I figured out the issue here, so will close this. Here's my thinking.
The referenced log above was from a change on stable/train: https://review.opendev.org/c/openstack/neutron/+/730888 Lajos fixed a bug in _find_available_ips that seems related: https://review.opendev.org/c/openstack/neutron/+/692135 commit 3c9b0a5fac2e3a1321eadc272c8ed46aa61efd3e Author: elajkat <[email protected]> Date: Wed Oct 30 13:38:30 2019 +0100 [fullstack] find ip based on allocation_pool _find_available_ips tried to find available ips based on the given subnet's cidr field, which can be misleading if random selection goes out-of allocation-pool. This patch changes this behaviour to use cidr's allocation_pool field. Closes-Bug: #1850292 Change-Id: Ied2ffb5ed58007789b0f5157731687dc2e0b9bb1 That change is only included in these versions: master stable/2023.1 stable/2023.2 stable/victoria stable/wallaby stable/xena stable/zed unmaintained/victoria unmaintained/wallaby unmaintained/xena unmaintained/yoga So I'm guessing merged in Victoria. Since the change was from stable/train we could have had an issue with the subnet['cidr'] being used, which would have included IP addresses outside the start/end allocation pool. ** Changed in: neutron Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!
