Hello,

This simple patch tests if the VTPM backend is present or not (if the
device file /dev/vtpm exists) and launch the backend listener only if it
is present.

So if you only run HVM domains you don't need to build and load the VTPM
backend (the module tpmbk). Of course, without the backend you won't be
able to use VTPM inside a pv DomU.

Cheers,
  Colin Didier
