This can happen if you have a machine without enough RAM, see this patch for details: https://review.openstack.org/#/c/234860/ It looks like we don't have that patch on stable/liberty, so I just proposed it as a backport: https://review.openstack.org/#/c/258397/ The workaround is either ensuring you have an undercloud with RAM of at least 12G or do export DIB_NO_TMPFS=1 before the image build.

It is also possible to just download pre-built images from our CI system
