Dmitry Tantsur e793cc4038 Remove virtualenv activation
Since the original merge of this code
(04208e7c79) several things have
changed; particularly now we ship dib-run-parts as part of dib, not as
a separate package.

We setup $_LIB to point to the shipped library diretory via
pkg_resources lookups.  We now call dib-run-parts (as mentioned,
shipped as a dib library now), source scripts, etc. via $_LIB and thus
do not rely on $PATH.  Consequently we don't need this activation
part.

Which is helpful, because "venv" (as opposed to virtualenv) doesn't
have activate_this.py.  So this fixes installation under that for
Python 3.

We update the functional tests to use the virtualenv_command exported
by the ensure-pip role, which will test the venv path.  There is no
need for dib_python as we are Python 3 only now.

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 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.
