Unfortunately this is the second time we've had to learn it :-( commit 5b9b49d7bd3e0da13e8f6d58578443a11817f56e Author: Paolo Bonzini <pbonzini@redhat.com> Date: Fri Jan 12 12:11:43 2018 +0100 docker: change Fedora base image to fedora:27 Using "fedora:latest" makes behavior different depending on when you actually pulled the image from the docker repository. In my case, the supposedly "latest" image was a Fedora 25 download from 8 months ago, and the new "test-debug" test was failing. Use "27" to improve reproducibility and make it clear when the image is obsolete.
