We introduced the "settle" in I90103b59357edebbac7a641e8980cb282d37561b thinking that maybe kpartx had not finished writing the partition. This probably wasn't a bad first assumption, since we used to have this -- but is seems insufficient. The other failiure here seems to be if kpartx hasn't actually seen the updated partition table in the image, so it has correctly (in it's mind) not mounted the partition. Looking at strace of fdisk run manually on a loopback, it will do a fsync on the raw device after writing and then a global sync as it exits. This replicates this; we flush and fsync in mbr.py in the exit handler after writing the partition, before closing the file (i've updated one of the unit tests to double-check the call). In the partitioning.py caller we execute a sync call too. Since it does seem unlikely the "-s" option of kpartx is not working, I've removed the udev settle work-around too.

Image building tools for OpenStack
diskimage-builder is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty based qcow2
image.
diskimage-builder is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
