So I do have now: 4 servers with 3.16 kernel and unoptimized ovs package 1 server with 3.13 kernel and unoptimized ovs package Will report back how it goes. cheers marco <http://www.nuvula.ch/> Marco Kuendig / CEO / Founder ma...@nuvula.ch <mailto:ma...@nuvula.ch> / +41 78 751 99 71 Marco's Google Hangout <https://plus.google.com/hangouts/_/nuvula.ch/marco> Nuvula AG - Hybrid Clouds Weierbachstrasse 7b 8193 Eglisau Switzerland http://www.nuvula.ch <http://www.nuvula.ch/> > On 22 Apr 2015, at 10:52, James Page <james.p...@ubuntu.com> wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > Marco > > Apologies for my foobar in not managing to provide un-optimized > binaries when I thought I had - apparently the ovs packaging > outsmarted me. > > I've push a verified -O0 build to ppa:james-page/openvswitch > > If you could retry with the latest packages from that PPA that would > be great - then we can really figure out whether this is an optimizer > issue or not... > > Regards > > James > > On 21/04/15 08:01, Marco Kuendig wrote: >> thanks James for the answer.
