[TPM, vTPM] Persistence of data on VM?
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...

OTOH for virtio if there's no implementation in a popular
hypervisor/language, we do ask for a somewhat detailed
spec.

Using TPM in dom0
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

[PATCH][vTPM] 3/3: TPM device model for qemu dm
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.

virsh support for TPM?
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 ??

[Xen] + [Libvirt] + [TPM]: can it work?
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
