The driver seems to function fine.  Image create/delete/clone is working, I have deployed VM's.  As it is a local storage driver, it will not be able to do live migrations.  I have not seen the stat script get called yet.

Maybe it's using the default one. Could you check your oned.log if
there is any message like this:
