[libvirt] [PATCH 10/12] qemu: Introduce code for blockdev-create
Peter Krempa
pkrempa at redhat.com
Thu Aug 8 16:00:40 UTC 2019
QEMU finally exposes an interface which allows us to instruct it to
format or create arbitrary images. This is required for blockdev
integration of block copy and snapshots as we need to pre-format images
prior to use with blockdev-add.
This path introduces job handling and also helpers for formatting and
attaching a whole image described by a virStorageSource.
