so you don't advise to use qcow2 as a VBD or what do you mean with "isn't
reliable"?
Right, qcow2 is both very slow with cache=writethrough (or off), and may
corrupt itself if the host crashes at the wrong moment.
or contrawise: on the other formats the metadata is updated in the
correct order?
raw is the only format we're sure of.
