Hi all!
After a lot of struggle I can now report a pretty serious bug in
the vtpmmgr 2.0 implementation:
- To make a the VTPM contents permenent, surviving a reboot
you have to seal the contents using the Pearl scripts in the
source directory calc.pl and manage-vtpmmgr.pl
- If you are using a TPM 2.0 HW TPM these seal operations
will still try to use TPM 1.2 commands for the seal and
it will fail
In other words you are not able to create a vtpm/vtpmmgr config that
survives a reboot if your HW is doing TPM 2.0
A showstopper for us..
Best
Dag
