I'm also concerned about the time is takes to run the external 'qemu-img create' command, which is non-trivial in some versions of qemu. In libguestfs, every millisecond counts.
qemu-img create is a thin wrapper for bdrv_create that would be done anyway by QEMU. So there is no difference apart from the cost of loading the binary.
Right -- that's the point though :-( Using qemu snapshot=on is free, since we've launched qemu already.
