This is a bug for either Vinnie Scarlata or Stefan Berger to look into, I
think. That code hasn't been touched in quite a while, so I'm not even sure
it's being actively maintained any more (in which case we'll remove it).

 Thanks for the bug report!

I've taken over vTPM maintainership from Vinnie and will have a look at
this today.  Please cc me on any future vTPM bugs or questions.

P.S.  It would be nice if the Bugzilla had a sub-component field that
could be used for finer-grained reporting (and also email notification)
of bugs.

Will do!

RE: Xen 3.0.5 Second Release Candidate

[Cihula, Joseph]

I've updated and re-assigned the bug back to Jan, but for those who are
interested and don't monitor Bugzilla:

I wasn't able to reproduce this with the -unstable tip.  As a BKM for
working with the vTPM system, one should always delete the
/var/vtpm/VTPM and /var/tpm/tpm_emulator-* files before starting any new
tests or debugging a failure.  If using the hardware TPM, then you might
also want to clear it so that the vtpm_manager can take ownership (it
works without this, but it guarantees that the SRK auth matches what the
manager expects).

That said, I did find a bug with failure to initialize a variable, and
I'll bundle that fix in with the 1.1b fix (shortly).

Xen 3.0.5 Second Release Candidate

[Keir Fraser]

Well, that didn't take long! This candidate fixes a regression which causes
32-bit x86 builds not to work out of the box (Xen is built for PAE, but the
Linux kernels are not). Also includes Tim Deegan's fix for SDL HVM
save/restore.

Available from the same place as before
(http://xenbits.xensource.com/staging/xen-3.0.5-testing.hg).
