Why are you even trying this again?  As explained very clearly last time you
can't change from a writeback-style to a write-through style I/O from
the monitor without creating massive data integrity problems.  See my
patchset that allows changing this from the guest for how it should be
done - I just need to get back and revisit the virtio protocol support
for it.
