Dear all, After applying the TPM patches to QEMU, I was wondering if it is possible to simultaneously use the TPM in more than one virtual machine, i.e. virtualisation of the TPM. According to the paper "Stefan Berger, Ramón Cáceres, Kenneth A. Goldman, Ronald Perez, Reiner Sailer, Leendert van Doorn. vTPM: Virtualizing the Trusted Platform Module" this seems to be possible in Xen. Is not possible in QEMU? Thanks! Jordi.
I don't think the pass-through driver supports use by multiple VMs. Stefan Berger should be able to answer better so I'm adding him to the thread.
