Julia Kreger 6739fa8ef4 Fix rhel/centos multipathing issues
Turns out the default VM images have basic support to handle even
multipathing. But might not contain the actual bits to enable the
kernel initial ramdisk to be regenerated at a later point in time
with those artifacts.

This creates a situation where a user could deploy the image on a
physical host, make other changes or perform an upgrade later, and
suddenly loose the ability to boot via multipath.

Alternatively, it also creates a situation where resulting DIB
images may explicitly loose multipath support where the base image
worked just fine.

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=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu

will create a bootable Ubuntu Bionic 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.
