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 http://xenbits.xen.org/docs/unstable/misc/vtpm.txt
I found the tpm emulator 0.7.4 and build it into centos 5.9 x64 PV vm.
I have access from that VM to the TPM as well via trousers.
What I cannot find is the vTPM manager that distributes vTpms to domains.
Is this feature deprecated ? Nobody anywhere is talking about it.
I am a little confused as there was measurement boot module supporting TXT boot released by citrix not long ago but there is no doc that can give me any info on how to/ or where from to get that management TPM software.
Best regards,
Jordan

The other places to read are: 1. the primary site at Berlios (this has of course gone dark) http://tpm-emulator.berlios.de/ I am not immediately sure where an external replacement now has moved to, but I have a mirror of that code about
2. the other two pieces of doco at the Xen site: http://xenbits.xen.org/docs/unstable/misc/vtpmmgr.txt
http://xenbits.xen.org/docs/unstable/misc/vtpm-platforms.txt
The flow of data is well described. What question is not clear from those diagrams
The final v 2 spec for tpm has recently been released, although 1.2 is still in deployment. see the TPM site

Those 2 other files give some other perspective of the things. Thanks.
What I cannot find is the following:
Compiling the Xen tree:
-----------------------
Compile and install the Xen tree as usual; be sure that the vTPM domains are
enabled when you run configure.
I use the Citrix XEN 6.2 + measurement boot addon and I don't have the vtpm manager installed on it. I don't know how do I enable vTPM domains at this point.
I am not sure where to look for the mini os for xen , I found this https://github.com/mirage/xen/blob/master/stubdom/vtpm/ which I think is the correct mini os + vtpm stubdomain.
So what I don't understand is how to install/enable vtpm manager on the citrix xen dom0?
Best regards,
Jordan
