From 435766502a1d23ed4c7304bbf5c33c6438ddc2cc Mon Sep 17 00:00:00 2001 From: Eduardo Olivares Date: Mon, 2 Dec 2024 17:12:31 +0100 Subject: [PATCH] Fix pep8 errors raised with python3.12 and update advanced guest image Two recent changes in CI infra have affected whitebox_neutron_tempest_plugin jobs: 1) After updating of pep8 jobs to ubuntu-noble/python3.12, an error is reported and this patch fixes it. 2) Tests using advanced images had issues to boot rocky 9.3 VM instances and due to that, this patch updates it to rocky 9.5. As a consequence of this change, virt-customize command has been updated to: * install tcpdump * enable dhcp for NetworkManager And some tests have been adapted to rocky 9.5 characteristics.
