This patch adds support for a volume format, which can be used for containers in Virtuozzo Server. This format is different from qcow2 images, because it consists of 2 or more files in a directory. The first file is an xml description of a bundle. It includes paths to base image and deltas, which usually stored in the same directory. Here is a description of base/delta images format - https://openvz.org/Ploop/format. Format name is a little ambiguous, because ploop is not only an image format name, but also a technology, which allows to use images, stored in files as block devices (like loop devices or qemu-nbd), but it supports snapshots and has nearly native performance. qemu-img has limited support of this format - it can only convert image files, the format is called 'parallels' in qemu-img. The main utility to manage such disks is 'ploop'. Here is a man page - https://static.openvz.org/vz-man/man8/ploop.8.gz.html. It can create images, make snapshots and create ploop devices, based on images. This patch series makes possible all volume operations except for snapshotting of 'in-use' volumes.
