Or if anybody come across this problem before please share some ideas.I google around for a few days already but so far I haven't got any luck.Note: the same nova, neutron and libvirt configuration work on Icehouse and Liberty on a different cluster, as i tested.ThanksPuthiNova Version tested: 2014.2.3 and 2014.2.4Nova Error Log============2016-01-14 17:34:08.818 6173 ERROR
