Hold your horses, all I've said is that I strongly agree that networks should be dynamically set from the engine, I did not comment on how. If there is a cross distribution utility out there that can do this in reliable <\bold> manner and actually offloads <\bold> logic from VDSM, meaning it's simpler then direct usage of mkdev, ip, brctl, etc to configure the hosts networking, it should be considered. What's important is the goal and not the way there. One of my goals, is returning to the stateless node concept the ovirt node had started with so many, many years (5?) ago. It just makes sense.

[vdsm] [PEP 8] About configuring editor plugins for checking PEP 8
Hi all, In the latest version of pep8 checking tool, the rules are very strict. Currently the VDSM project applies a less strict rule set by suppressing some errors from pep8. You can find them at Makefile.am . Under the "check-local:" target, you will see --ignore=E121,E122,E123,E124,E125,E126,E127,E128,E241 I know some of us using editor plugins to check pep8 erros. Those plugins invoke flake8/pep8 and report errors. To ignore some rules not needed by VDSM in the editor, create a file in ~/.config/pep8 and input the text as follow. [pep8] ignore=E121,E122,E123,E124,E125,E126,E127,E128,E241 -- Thanks and best regards!

The only point for my adding this exceptions was that vdsm would otherwise not build on Fedora 18. I would like to see our code fully confrming to the standards.

I couldn't disagree more. What you are suggesting requires that we reimplement every single networking feature in oVirt by ourselves. If we want to support the (absolutely critical) goal of being distro agnostic, then we need to implement the same functionality across multiple distros too. This is more work than we will ever be able to keep up with. If you think it's hard to stabilize the integration of an external networking library, imagine how hard it will be to stabilize our own rewritten and buggy version. This is not how open source is supposed to work. We should be assembling distinct, modular, pre-existing components together when they are available. If NetworkManager has integration problems, let's work upstream to fix them. If it's dependencies are too great, let's modularize it so we don't need to ship the parts that we don't need. -- Adam Litke IBM Linux Technology Center ___ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel
