just an update for this question. the issue is resolved with a kernel update

Also this kernel change does not seem to have broken anything else in openstack -- Jim On Fri, Nov 10, 2017 at 9:50 AM, Jim Okken <j...@jokken.com> wrote: > ===== UPDATE 11/10 ====== > hi again, > > based on some advice from a member of this mailing list we've been looking > into kernel and driver versions of our compute nodes > > We also have plain non openstack "KVM on Ubuntu" servers for testing. > > I looked at driver and kernel differences between these Ubuntu 16 w/ KVM > systems and our openstack compute nodes.
