[Xense-devel] [Q] about vTPM

[Atsushi SAKAI <sakaia@xxxxxxxxxxxxxx>]

I have several questions on vTPM implementation on Xen.
I would be appreciated if you answer the questions.

1.GVTPM is seems like ideal model of current vTPM implementaion.
  Is this true?
  (for example, securestorege.c is in vtpm_manager)

2.I think vTPM key functionality is migration of vTPM instance.
  But It seems not implemented. Is this true?
  It seems like the migration key is the builtin HW-TPM function only.

3.Currently vTPM implementaion is only ParaVM.
  Is there any plan to support FullVM?

4.vtpm document(docs/misc/vtpm.txt) is little bit old.
  So the documentation does not infar the Infineon chip.
  I think Infineon chip is supported.
