Hello, Just a heads-up; with Fedora 29 the legacy networking setup was moved into a separate, not-installed-by-default network-scripts package. This has prompted us to finally move to managing interfaces on our Fedora and CentOS CI hosts with NetworkManager (see [1]) Support for this is enabled with features added in glean 1.13.0 and diskimage-builder 1.19.0. The newly created Fedora 29 nodes [2] will have it enabled, and [3] will switch CentOS nodes shortly. This is tested by our nodepool jobs which build images, upload them into devstack and boot them, and then check the networking [4]. I don't really expect any problems, but be aware NetworkManager packages will appear on the CentOS 7 and Fedora base images with these changes.
