The release of pip10 has shown up a few issues here Firstly, pip10 now refuses to overwrite distutils installed packages, which includes "python-virtualenv" on centos. History has shown us that we want the packages installed and overwritten, to avoid the packages coming back and messing things up. Pre-install all the packages, then list the files in the packages with "rpm" directly and remove them. This way pip is happy to install. We need to take better account of the package names for this; on Fedora things have switch to "python2-virtualenv" instead of "python-virtualenv" and we can't use an alias to list the package contents. This also highlighted that python2-pip is in EPEL for centos, so enable that when we install it. Make the epel element a no-op for non centos/rhe distros. There is a related change in recent fedora that python3 now installs binaries into /usr/local/bin. There are commented swizzles in here to ensure we retain the status quo of "pip" and "virtualenv" both being python2 based, with the python3 versions being called explicitly "pip3" and "virtualenv3" respectively.

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 ubuntu
will 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.
