NOVA is a modern open-source ARMv8-A and x86_64 microhypervisor that can host and harden unmodified guest operating systems. In this talk I will give an overview of the new features that have been added to NOVA in 2023 to enable it to scale from small embedded devices (e.g., Raspberry Pi) to big-iron servers (e.g., AWS cloud instances). In the second half of the talk, I will present the implementation of Intel Trusted Execution Technology in NOVA and how NOVA leverages the TPM to establish a Dynamic Root of Trust for Measurement (DRTM) that extends all the way into a user-mode component-based OS.
