+# 1. Non-secure VMs run on emulated environments like Cuttlefish, which lack

+#    is passed into the VM from the host's HAL, and an RPMB proxy provides
+#    secure storage.
+# 2. Secure VMs run on physical devices. Here, pVM firmware handles the
+#    transfer of root-of-trust data via DeviceTree, and a TEE provides secure
+#    storage.
