The only possibly relevant change I can see in 2.3 is that the qcow2
driver added an additional error check to a truncate operation. Can you
please run qemu-img under strace -f and either provide the output as an
attachment or paste the relevant failing call(s) if you can recognise
them?

Bug description:
  Hello guys,

      There seems to be a bug in qemu-img with 2.3.0 that wasn't there
  in 2.2.1  .... qemu convert will always fail converting.  See the
  output below:
