Hi , Thank you very much for your reply, I also would like to ask a question about the vTPM in this paper(vTPM: Virtualizing the Trusted Platform Module , http://domino.research.ibm.com/library/cyberdig.nsf/papers/A0163FFF5B1A61FE85257178004EEE39/$File/rc23879.pdf). Is there an open-source and concrete implementation of its 'vTPM instance migration'?
