I think you can avoid modifying all the image formats:
.bdr
Add 'nocow' create option so that users could set nocow flag to newly created
images, which could solve performance issues on btrfs.
Btrfs has terrible performance when hosting VM images, even more when the guest
in those VM are also using btrfs as file system. One way to mitigate this bad
perform
