Hi, I‘m trying to install vTPM based on Xen-4.2.2, linux-kernel 3.9.1 (Dom0) and TPM emulator. However, I cannot find the TPM backed driver in this version of Dom0 linux kernel. There is no CONFIG_XEN_TPMDEV_BACKEND in the kernel config file. The config file for Dom0 is attached. Maybe it provides some useful information. So, h...

Hi everyone, I am using Xen 3.2.1 with the vtpm-12-patch.diff patch posted in [0]. My TPM is an Infineon 1.2. In total I have got three different questions: 1. NVM loading problem at VM creation When I am creating a VM the last few lines of the vtpm_manager output are: TPMD[245]: tpm/tpm_startup.c:45: Info: TPM_Startup(1) Loading NVM. S...

Hi community, there are some problems to start vTPM vtpm-stubdom following docs/misc/vtpm.txt. When I start vtpm-stbdom, the vtpmmgr-stubdom will print out: === ERROR[VTPM]: LoadKey failure: Unrecognized uuid! 69743ae0-9d4a-4ad6-9819-e602085b6792 ERROR[VTPM]: Failed to load key ERROR in vtpmmgr_LoadHashKey at vtpm_cmd_handler.c:78 code: TPM_BAD_PARA...

Hi all! Just setting up a cluster using Centos 7 We have a desperate need for TPM support and: 1. Tried the "standard" distro install. linvirt supports TPM passthrough but kvm-qemu barfs: "unsupported configuration: The QEMU executable /usr/libexec/qemu-kvm does not support TPM backend type passthrough" 2. The activated the qemu-ev repo and updated qemu...

Hi All, Please read the following steps involved in installing and configuring my Xen box with V-TPM enabled, which I am not able to make it work. Host Linux Distro - CentOS 4.1 Guest Linux distros - Centos 4.1, SUSE TPM module - TPM emulator Downloads: gmp-4.1.4 xen-instable-src.tgz (downloaded on 29/9/2005) bridge-utils-1.0.6.tar.gz compiled and installed gmp-4.1.4 and bridge-utils. Now comi...

What I?m saying is that TPM should be able to behave like a PKCS#11 token. Loading TPM keys is similar to provisioning a PKCS#11 token (and hopefully needs to be done as rarely). The normal use of a TPM seems to be operating on the keys already installed ? rather than loading keys in every time you need to do something. TPM,...

has anyone implemented any sort of 'secure boot' using TPM 1.2 modules on the server boards using CentOS 6.x ? I'm not finding much concrete stuff on how to setup and manage a system like this, but I've been asked to research it for a security application internally at my job. our primary application for the TPM is for client authentication...

Hi, I am currently running a Debian lenny on top of a Ubuntu 9.04 dom0. (Xen version is 3.4) Now I want to test some tpm functions in the domU, but I am having troubles reaching the TPM. To do so, I am following the tutorial here : https://www.grounation.org/index.php?post/2008/07/04/8-how-to-use-a-tpm-with-linux I have already used this tutorial on a non-virtualised machine, and even on my dom0, and I managed to c...
