hi, I try to load front-end tpm driver, but there is no /dev/tpm0 in DomainU. I use redhat5 and add tpm_vtpm.c+ tpm_xen.c by myself. Has anybody sucessfully loaded front-end tpm ? Could u please give the detailed steps? and Could u please tell which file create /dev/tpm0 in DomainU? thank a lot. --Yaody CHANG _______________________________________________ Xen-devel mailing list

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

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.

Dear, We released VMKNOPPIX(20070328) with Trusted Boot. http://unit.aist.go.jp/itri/knoppix/vmknoppix/index-en.html VMKnoppix is a collection of Virtual Machine Software, Xen, KVM, VirtualBox, QEMU, KQEMU(QEMU with Accelerator) and UserModeLinux. This version includes "Trusted Boot" (Trusted GRUB and IMA: Integrity Measured Architecture). === Features

I am removing the experimental feature that allows buffer sizes for transfers from TPMs larger than 2kb. This could become useful if a vTPM is located in its owns domain and needs to be serialized for suspension or migration and the packet size becomes bigger than the current limit. Partial reads were supposed to complement this feature for applications to know how many bytes to read from

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, how to install a Xen TPM backend driver in the Dom0 linux-kernel.

This patch adds a TIS device model compliant to the 1.2 TPM specification to Qemu. It implements all registers necessary to make the Linux TIS driver work (tpm_tis.c). All of the basic registers supported by this type of device are implemented. Also the locality selection has been implemented, but has not been tested. The legacy registers as described in the specification are not supported.

When redirecting the output of the echo command using ''>'' on bash, the output seems to be broken up into multiple write()s (depending on the version of busybox?). Unfortunately /dev/tpm0 needs to have the complete command written to in one chunk. The work-around ''echo <string> > file ; cat file > /dev/tpm0'' seems to get around this problem. The

I can get vtpm_manager to run if I delete /var/vtpm/VTPM. However, when I kill it with control-c, and try to run it again, I get: INFO[VTPM]: Starting VTPM.

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.

Hi, I am following http://xenbits.xen.org/docs/unstable/misc/vtpm.txt, but I''m having some problems when I try to start vtpmmgr-stubdom I''m using Xen 4.3 on Ubuntu 12.04 and I have a physical TPM. The config file for vTPM manager is: kernel="/usr/local/lib/xen/boot/vtpmmgr-stubdom.gz" memory=16 disk=["file:/var/vtpmmgr-stubdom.img,hda,w"]

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

What will follow soon are updates to vtpmd, vtpm_manager, xm, xl, mini-os, and new vtpm and vtpm manager stub domains. The first patch I''d like to submit upgrades vtpmd to version 0.7.4 This patch does the following: -add checks to configure to check for cmake (required by berlios 0.7.4) -removes all of the 0.5.1 patches -adds a single patch for 0.7.4 -cleans up the makefile, should

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
