[Qemu-devel] [PATCH 0/3] Change the backing file of images

[Kevin Wolf]

This patch series adds the functionality to change the backing file of existing
images. This includes simple renaming of a backing file without converting the
COW image as well as safe rebasing onto a different backing file that has some
changes compared to the current backing file.
