Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,

The user has the option of disabling the platform driver: 00:02.0 Unassigned class [ff80]: XenSource, Inc. Xen Platform Device (rev 01) which is used to unplug the emulated drivers (IDE, Realtek 8169, etc) and allow the PV drivers to take over. If the user wishes to disable that they can set: xen_platform_pci=0 (in the guest config file) or xen_emul_unplug=never (on the Linux command

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.

Hi, In Fedora 8 kernel source code, I could find tpmback.c in drivers/xen But where is tpmfront.c? in old distribution? thank for any help. superbobo _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Dag, Thanks for tracking this down. Any chance you could send a PR to https://github.com/CentOS-virt7/xen-kernel? Otherwise, Anthony or I will take a look when we get a chance.

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 ?? Best Dag

Hi community, there are some problems to start vTPM vtpm-stubdom following docs/misc/vtpm.txt.

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

Problems start before any of the kaiser code executes, though it could still be related to CONFIG_KAISER since that has effects beyond kaiser.c. --- (early) Initializing cgroup subsys cpuset (early) Initializing cgroup subsys cpu (early) Linux version 2.6.32-696.18.7.el6.x86_64 (mockbuild at c1bl.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) ) #1 SMP Thu Jan 4 17:31:22 UTC

Hello, I'm was looking through handbook and wikipedia and it appears FreeBSD doesn't support hardware (nor software) nx bit. There also doesn't seem to be any support for TPM (Trusted Platform Module). I was wondering if it is due to a general lack of interest and/or personal preference (gcc?) or are there other issues. The reason I'm asking is I'm currently doing a MSc degree

has anyone implemented any sort of 'secure boot' using TPM 1.2 modules on the server boards using CentOS 6.x ? I'm not finding much concrete stuff on how to setup and manage a system like this, but I've been asked to research it for a security application internally at my job. our primary application for the TPM is for client authentication certificates in an SSL application

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,

Nice attitude and helpfulness in this list! Just had a look and it doesn't seem to be that an intrusive

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
