Hi, i am using Xen 3.2.0 and want to use the TPM in dom0. I have activated vtpm and everything runs fine in my domUs. The question is, how can I access the TPM in dom0? As far as I know vtpm_managerd exclusively locks /dev/tpm0. As soon as I start vtpm_managerd my own program cannot access the TPM anymore. Is there a vtpm instance for dom0 like the ones for the user domains? Thanks in advance for any hints, Tom -- GMX startet ShortView.de. Hier findest Du Leute mit Deinen Interessen!

The vtpm_manager is designed to be the only application accessing the TPM in dom0 - as by design and for many security reasons. Eventually you should post your request to xen-devel and see if there have been any recent developments on this.
