Re: [libvirt] [PATCH 18/19] qemu: backup: Merge bitmaps accross the backing chain

To allow backups work accross external snapshots we need to improve the

algorithm which calculates which bitmaps to merge. The algorithm must look for appropriately named bitmaps in the image and possibly descend into a backing image if the current image does not have the bitmap.
