     I got an error when starting vtpm_manager:

INFO[VTPM]: Starting VTPM.
INFO[TCS]: Constructing new TCS:
INFO[TCS]: Calling TCS_OpenContext:
INFO[VTSP]: Loading Key into TPM.
ERROR[TCS]: TCSP_LoadKeyByBlob Failed with return code TPM_KEYNOTFOUND
ERROR in VTSP_LoadKey at vtsp.c:634 code: TPM_KEYNOTFOUND.
ERROR in VTPM_LoadManagerData at securestorage.c:453 code: TPM_KEYNOTFOUND.
ERROR[VTPM]: Failed to load service data with error = TPM_KEYNOTFOUND
ERROR[VTPM]: Failed to read existing manager filepuppy:/sys/class/misc/tpm0/device

     I am sure the tpm is working, because initially it has windows on it and I just format and reinstall xen and debian etch. The first time I tried to start vtpm_managerd, there was some error like TPM_IOERROR and unable to take ownership. That's because the windows system already took ownership of it. So I just cleared the TPM in the bios and restarted vtpm_managerd, and got the above error. Everything is fine before starting vtpm_manager. It loaded the tpm driver and backend driver OK in dom0.

     I read the related topics in the forum and found a related thread here: http://lists.xensource.com/archives/html/xense-devel/2006-12/msg00016.html
     The conclusion in that thread is that the 1.2 tpm does not support depreciated APIs, while vtpm_managerd still uses it.

      I am not sure if this is that case in my problem. Here's my system configuration:

      Thinkpad T60p
      Xen 3.2.0
      Debian etch
      TPM: Atmel 1.2
      TCG version : 1.2
