Xen has/had something where (IIUC) the kernel would call out on an
unmapped cluster, let userspace figure out the mapping, then service
requests to that cluster completely in the kernel.  I'm not convinced
it's worthwhile.

btw, the kernel already has support for a flexible copy-on-write format
- btrfs raw files.  It makes sense to increase the integration there. 
You can keep image files as ordinary files, use COW for snapshots, and
implement exporting to qcow via SEEK_HOLE.
