This patch is intended to start a slightly larger discussion about our plans for the CentOS CI environment going forward. At the moment, we have active builders for CentOS 7 Debian 9 Debian 10 Fedora 30 Fedora 31 Fedora Rawhide FreeBSD 11 FreeBSD 12 but we don't have builder for Debian sid FreeBSD -CURRENT Ubuntu 16.04 Ubuntu 18.04 despite them being fully supported in the libvirt-jenkins-ci repository. This makes sense for sid and -CURRENT, since the former covers the same "freshest Linux packages" angle that Rawhide already takes care of and the latter is often broken and not trivial to keep updated; both Ubuntu targets, however, should IMHO be part of the CentOS CI environment. Hence this series :) Moreover, we're in the process of adding CentOS 8 openSUSE Leap 15.1 openSUSE Tumbleweed as targets, of which the first two should also IMHO be added as they would provide useful additional coverage. The only reason why I'm even questioning whether this should be done is capacity for the hypervisor host: the machine we're running all builders on has CPUs: 8 Memory: 32 GiB Storage: 450 GiB and each of the guests is configured to use CPUs: 2 Memory: 2 GiB Storage: 20 GiB So while we're good, and actually have plenty of room to grow, on the memory and storage front, we're already overcommitting our CPUs pretty significantly, which I guess is at least part of the reason why builds take so long. Can we afford to add 50% more load on the machine without making it unusable? I don't know. But I think it would be worthwhile to at least try and see how it handles an additional 25%, which is exactly what this series does. In my opinion, as long as the machine can keep up with demand and not end up in a situation where it starts accumulating backlog jobs, it's fine if builds take longer: developers who want to run a relatively quick smoke test before posting patches can use Travis CI or 'make ci-check@...' locally for the purpose, whereas the role of CentOS CI in my eyes is to try and catch as many issues as possible after merge so that they don't end up in a release. But I realize others might see it differently, hence this lenghty cover letter :) Andrea Bolognani (1): jenkins: Start building on Ubuntu jenkins/jobs/defaults.yaml | 2 ++ jenkins/projects/libvirt-dbus.yaml | 1 + jenkins/projects/libvirt-sandbox.yaml | 2 ++ jenkins/projects/libvirt-tck.yaml | 2 ++ jenkins/projects/libvirt.yaml | 2 ++ jenkins/projects/virt-manager.yaml | 2 ++ 6 files changed, 11 insertions(+) -- 2.23.0 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
