You change the cache mode using a custom property per-VM I believe. I
don't know if this would work for the hosted engine.
I've already downgraded my system, but once you have the test machine up,
perhaps you can try it. The custom property would be:
viodiskcache=writethrough
or
viodiskcache=writeback
