No clue yet, but interested as well. Although I avoid these spaced qcow-files anyway. I would like to run QEMU/KVM-based VMs on btrfs subvolumes ... I love the idea of snapshotting them. Until now I often run them on LVM-LVs (as "raw") and use virt-backup (which uses LVM snapshots) to generate backups. That works OK but btrfs-snapshots look and are way more sophisticated, I assume. - - I currently move over data from my zfs-pool to a new btrfs pool and will remove zfs then from that server.
