This patch series provides persistent storage support that a TPM
can use to store NVRAM data. It uses QEMU's block driver to store
data on a drive image. The libtpms TPM 1.2 backend will be the
initial user of this functionality to store data that must persist
through a reboot or migration. A sample command line may look like
this:
qemu-system-x86_64 ...
-drive file=/path/to/nvram.qcow2,id=drive-nvram0-0-0
-tpmdev libtpms,id=tpm-tpm0
-device tpm-tis,tpmdev=tpm-tpm0,id=tpm0,drive=drive-nvram0-0-0
Thanks,
Corey
