The newer version of the emulator contains several bug fixes, one that we were seeing in our use of vtpm. This patch also defines TPM_STRONG_PERSISTENCE for the new emulator. A couple of important notes about this patch: -This has only been tested on PVM domU's. In theory it should work for HVM but I have not tried it at all and can guarantee nothing. -All the relevant changes in tools/vtpm/vtpm.patch have been ported to tpm_emulator-0.5.1. -None of the changes in tpm_emulator.patch have been ported. In particular this means the BUILD_EMULATOR option, which as I understand lets you use the tpm_emulator in dom0 for a machine that does not have a real hardware TPM does not work. This functionality should be easy to add though because the new emulator already comes with a kernel module interface. -No considerations were made for the VTPM_MULTI_VM feature (which is supposedly unfinished). This patch may or may not break any progress made on that feature. Signed-off-by: Matt Fioravante <Matthew.Fioravante@jhuapl.edu>
