similar to: TPM support in Syslinux

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

Syslinux 6.03 (efi64) fails to boot a 32-bit kernel. The way Syslinux leaves long mode in kernel_jump assembly routine does not follow AMD64 specifications. More precisely: 1. After setting a new GADT, `cs` has to be refresh by doing a long jump, but it is not 2. Other segments have to be updated, but they are not 3. Disabling paging has to be done before disabling long mode, but the

Hi, I'm trying to get to the bottom of a problem using the combination of tboot (http://tboot.sf.net, trusted boot kernel for Intel TXT) and extlinux. TBOOT loads using the multiboot protocol, where the tboot "kernel" is loaded as the kernel, and the actual linux kernel and initrd are specified as modules. A working grub configuration looks something like:

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. Sending LoadNVM command ERROR[VTPM]: Failed to load

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

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

Hello everyone, With the computers equipped with TPM chip popularizing, many OS begin to support it. And Linux and Vista are some of then. I want to know whether the FreeBSD Project has a plan to support it and some related technology. Can anyone answer me?

That's a great question, actually, I should have remembered to mention that! You can control what factors are used for the TPM's integrity check to release the bitlocker key on boot. Depending on whether your on a BIOS or EFI machine, there are slight differences, but definitely controllable by group policy. http://technet.microsoft.com/en-us/library/ee706521(v=ws.10).aspx#BKMK_depopt3 I

Hi all, How the virtual TPM dispatch TPM commands ? I know that If multiple virtual machines send TPM commands to the virtual TPM, it can be determined from the instance number of a TPM command from which VM the command originated. My question is how the instance number of a TPM command can be prepended? thanks _______________________________________________ Xen-devel mailing list
