Of course not, since we no longer support that mode why would it?

I think basically you will need to understand how this stuff fits
together and then implement the required xl support, there are unlikely
to be any short cuts or quick hacks. Certainly you will have to do a lot
more leg work such that you are able to ask more specific technical
questions.

Because we will hit the deadline, we don't have much time to work on the vTPM.

Well, it seems there is huge amount of work to make xl support the old vTPM.

Oh, in your opinion, is it possible to make xm re-work in the Xen-4.3-unstable in short time? If it's possible, maybe we can use xm to support the old vTPM in the latest Xen. Thanks a lot.
