Since libvirt 4.5.0-10.el7_6.3 from RHEL-7.6 is incompatible with ceph 0.94.5 from ceph 1.3 repos, we rebuilt the overcloud images using the content from ceph 2.0. The new overcloud images build is rhosp-director-images-8.0-20180928.1.el7ost.

The phase1 tripleo job is failing to deploy the overcloud using these new images.

osp8 has not been tested with ceph 2.0, so iiuc we need backports to tht and puppet-ceph (at a minimum).

In output from os-collect-config in /var/log/messages on controller-0, I see this error (I've cleaned up the error formatting in this paste):
