Christophe: In case you hadn't seen what Max is referring to on the
qemu-img man page:

  -p  display progress bar (compare, convert and rebase commands
      only).  If the -p option is not used for a command that supports
      it, the progress is reported when the process receives a
      "SIGUSR1" signal.

Does this do what you want?
