Thus , we don't use paravirtualization and we
can run unmodified guest.
  Is there a possibility or any intention of using the
backend-frontend solution of Xen (maybe with some fixes) when using
VT-x processors ? wouldn't it be much better in terms of
performance than using hardware emulation (based on QEMU maybe)?

Yes. PV drivers are a prerequisite for decent performance for fully virtualized guests on xen.
