Thanks Avi,

I am still trying to reconcile the your statement with the potential
data risks and the numbers observed.

My read of your response is that the guest sees a consistent view -
the data is commited to the virtual disk device.  Does a synchronous
write within the guest trigger a synchronous write of the virtual
device within the host?

Yes.

I don't think offering SQLite users a 10 fold increase in performance
with no data integrity risks just by using KVM is a sane proposition.

It isn't, my guess is that the test setup is broken somehow.
