Hi. I am very interested in the security properties a totally open TPM can give our users? - its use as a universal smartcard to protect all types of keys. When adding the virtual 1.2 or 2.0 TPM I get the vague error below. OS is Debian stable with standard packages. Error starting domain: Unable to find 'swtpm' binary in $PATH: No such file or directory Traceback (most recent call

Hi, I would like to clarify how to make snapshots of running VMs with emulated TPM devices. As far as I understand QEMU documentation, it's possible to make snapshots of running VMs with TPM, but it's important to retain the state of swtpm. Does libvirt assist with that in any way or is it completely user's responsibility? libvirt pauses the VM internally when making a snapshot,

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-kvm to version

I want to install tpm emulator simulating the TPM hardware in Xen platform. But compiling tpm emulator brings such error.My kernel is 2.6.16. #make ; make install ......... Building modules, stage 2.

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

Sorry, the other patch was broken. I type-o-ed in the patch creation process and made a big patch of stuff already checked in.
