Yep - deltarpm uses bsdiff and they struggle to diff so large binary files. If we had a different deliverable - like a tarball - then bsdiff could make sense. But a qcow is not an ideal format for doing a binary diff. Btw a squashfs is also not suitable for bdiff. - fabian > It may take a little more tweaking, but the options for "makedeltarpm" are > pretty sparse.
