The block device lvm lvs `size` attribute was passed directly to lvcreate, so using units M, G means base 2. All other block device size values are parsed with accepted conventions of M, B being base 10 and MiB, GiB being base 2. lvm lvs `size` attributes are now parsed the same as other size attributes. This improves consistency and makes it practical to calculate volume sizes to fill the partition size. This means existing size values will now create slightly smaller volumes. Previous sizes can be restored by changing the unit to MiB, GiB, or increasing the value for a base 10 unit. The impact on this change should be minimal, the only known uses of lvm volumes (TripleO, and element block-device-efi-lvm) uses extents percentage instead of size. The smaller sizes can always be increased after deployment. Requested sizes will also be rounded down to align with physical extents (4MiB). Previously specifying a value which did not align on 4MiB would consume an extra extent which could unexpectedly consume more than the partition size.

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 ubuntuwill 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.
