I think it is fair to read the PCRs before performing Deep Quote and after
and
to retry if something changed.
It is an interesting suggestion to extend the tpm character device driver
in order
to obtain atomicity. I will think about it.
Thanks for clarifying.

I am trying to validate a Deep Quote request made by domU but I feel that
something is missing. Right now

I am trying to validate a Deep Quote request made by domU but I feel that
something is missing. Right now when a domU requests TPM_ORD_DeepQuote:
1. vTPM:
