+Create folder under /tmp/volume/host_<host name> for each host (example
+host_sample where sample is the name of the tpm capable host).
+This folder will be mounted into the container as shared volume for now.
+
+Expects the input SRK pulic key "out_parent_public" for each host under
+the corresponding host directory and file "passphrase" under /tmp/volume/
+containing the passphrase to encrypt the key.

+  /tmp/volume/host_sample/out_parent_public
