Hi, Guan

       Could you enable vTPM now?  My vTPM is always print out below error when I enable vtpm-stubdom.


ERROR[VTPM]: LoadKey failure: Unrecognized uuid! f70b429c-c7e4-41be-948f-76991f57a3bf

ERROR[VTPM]: Failed to load key

ERROR in vtpmmgr_LoadHashKey at vtpm_cmd_handler.c:78 code: TPM_BAD_PARAMETER.



Could you share some experience?  Thanks in advance.

I'd like to use some advanced functions of vTPM, such as migration. So, I try to port the old version of vTPM tools (tools/vtpm and tools/vtpm_manager in Xen-3.4.2 ) to Xen-4.3 unstable.


Now, the vtm-manager can communicate with vtmd, but DomU cannot boot when it's configured with a vtpm option in the config file. I think maybe xl doesn't support the old vTPM tools very well. If this is the case, can you give me some advice on how to modify the xl to support the old vTPM?


Thank you very much.


Best Regards,

Bei Guan
