Dear all, I am trying to compile Xen 4.2.0 with VTPM support. The documentation available inside Xen is from 2006. I am wondering if the current steps to enable VTPM support are the same written in the documentation or they have changed. Is it enough with setting the "--enable-vtpm" argument during the configure process? Furthermore, at that time Xen was providing the Linux Kernel as part of its sources. Have the current kernels to be patched to include the Xen VTPM drivers? If it is the case, where can we find the patches? Thank you in advance! Jordi.
The current (old) vtpm implementation still sort of works. You have to use xm and find a linux kernel with the tpmfront and tpmback drivers. I believe the original xen 2.6.18 kernel has them. There may or may not be newer kernels with these drivers. docs/misc/vtpm.txt should have everything you need to use it. That being said I''m in the process of submitting my new vtpm implementation. So keep an eye on that activity if you''re interested. On 09/27/2012 11:40 AM, Jordi Cucurull Juan wrote:> Dear all, > > I am trying to compile Xen 4.2.0 with VTPM support.

Hi Matthew, As a rough approximation, when are you planning to submit the new vtpm implementation? In the new coming weeks, months, year? And, is this new vtpm going to be linked to the physical tpm of the machine or is going to be totally independent of it?

It uses the physical tpm. Hopefully they should all be in within a month. Were working on it now.
