Adds a check to vtpm_manager and vtpm Makefiles to verify openssl and
...
gmp dev files are installed. If files are missing, Makefile exits with a
message indicating that these tools will not be built, rather than an
error, which prevents Xen from building.

Virtual TPM persistent states contain VTPM secrets, which are encrypted
...
using symmetric keys and stored on disk along with those symmetric keys.
The attached patch uses the TPM to encrypt the symmetric keys and other
global secrets before saving them to disk.

Add 64 bit support to the VTPM Tools plus do some minor cleanups.
...
The VTPM manager and VTPMs fully support both 32 and 64 bit OSes. The
tpm_emulator (provided for debugging on TPM-less machines) does not
support 64-bit kernels by default though. See the README for details on
how to use it on 64-bit kernels.
