Above command only pre-allocates metadata, so creation is still fast?
If so, we can do that by default, because metadata is small (128MB/TB).

Well, I finally asked the developer if he can update the code to make it work
with current qemu, but got no answer then. I thing he is not willing to do that.
I also tried myself, but the code is simply too old, so it would require much
work to get that working (maybe several weeks?).
