similar to: How to get the instance number from TPM Command in VTPM

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

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 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.

Hello everyone, I am sorry for interrupting your work I am following the correspondence in silence. I am trying to build a vtpm implementation into xen 6.2 but I was not able to find all the means to do it. What can be found is just abstract knowledge. Most of the info always forwards me to this doc

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

The following are a set of patches to run the berlios tpm emulator 0.6.1 in a mini-os domain, called vtpm-stubdom. Documentation on how to use this domain is located at stubdom/vtpm/README. The following are a series of patches that enable this domain and also add significant stability improvements to the entire vTPM subsystem, including the original method of using vtpmd as a process.

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.

Virtual TPM persistent states contain VTPM secrets, which are encrypted using symmetric keys and stored on disk along with those symmetric keys. The attached patch uses the TPM to encrypt the symmetric keys and other global secrets before saving them to disk.

This patch should be applied the source tree once the 2.6.16-rc4 or 2.6.17 or a later kernel is used. I am sending it now in order not to break the build when switching. I am updating tpm.c and tpm.h to follow the changes in mainline. As a result of the patch, all changes to these two files (when compared to mainline) are surrounded by #ifdef CONFIG_XEN. Since now the chip structure is returned

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
