Hi, I have a problem in creating a connection between vtpmmgr and vtpm. First the vtpmmgr is booted correctly and "waits for vTPM''s command". However, when the vTPM is launched, the connection with vtpmmgr is not (apparently) established. I get the following error message in vtpmmgr and after that the vtpmmgr goes to "waiting for commands" state. ================message: ================INFO[VTPM]: Waiting for commands from vTPM''s: Tpmback:Info Frontend 16/0 connected INFO[VTPM]: Passthrough: TPM_GetRandom INFO[VTPM]: Waiting for commands from vTPM''s: INFO[VTPM]: Passthrough: TPM_GetRandom INFO[VTPM]: Waiting for commands from vTPM''s: ERROR[VTPM]: LoadKey failure: Unrecognized uuid! d88e5a73-982d-4354-ab11-e5d70a8ee895 ERROR[VTPM]: Failed to load key ERROR in vtpmmgr_LoadHashKey at vtpm_cmd_handler.c:78 code: TPM_BAD_PARAMETER.
