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

Hi, In advance, sorry, I am not sure if it''s the right mailing list to ask that, but as my question is half-way between Xen and trousers, I thought asking in both mailing lists would not be too much.... I am currently having a little problem finding out how to make work my seal/unseal things... Running a Debian Lenny on top of Xen 3.5 unstable. with vtpm management enabled on my

No need for TCG level spec for this :-) OTOH for virtio if there's no implementation in a popular hypervisor/language, we do ask for a somewhat detailed spec.

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 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

This patch adds a TPM device model to the qemu dm for fully virtualized VMs. It is enabled in the VM only if the user requests a TPM device in the vm configuration file using the ''vtpm=[...]'' line. It enables the qemu device model command line with a ''vtpm_instance <instance number>'' parameter. Signed-off-by: David Safford <safford@watson.ibm.com>

Hi again! Succeeded in creating vtpmmgr-stubdom.gz from the source RPM with some shortcuts. ow the next problem seems to be that the libvirt we have will not support the XEN vtpm:s For example: virsh dumpxml <vm-machine> will not contain any info on the vtpm :-( Am I really the first one around with a need for TPM support in the VM:s ??

I am trying to get TPM 2.0 pass through to work with Xen and libvirt, but I can't get it to work. According to the following sites both Xen and libirt have TPM 2.0 support. https://wiki.xen.org/wiki/Virtual_Trusted_Platform_Module_(vTPM) https://libvirt.org/formatdomain.html#elementsTpm However, when I add a TPM device to a VM (by virt-manager), the VM guest XML does contain the TPM
