Certain parts of the implementation are not specific to any model.
Specifically the driver pair that IBM contributed and the common portion
of the vtpm management scripts. However, you are correct in the
observation that the vtpm_managerd contributed by Intel is an
implementations of the GVTPM model.

VTPM Migration support in the vtpm_managerd is nearly complete and I
will be submitted to the tree soon.
