Re: [Xen-devel] vTPM Manager

[Matthew Fioravante <matthew.fioravante@xxxxxxxxxx>]

You can also try to use my updated vtpm manager patches which fixes a
lot of bugs. I haven't tried them on the latest xen unstable but they
worked with xen at the time they were submitted. They have not been
accepted by the developers yet. You should be able to find my earlier
posts in the mailing list archives
