There are numerous open source hypervisors with small and easy-to-study implementations, but those that support booting operating systems as UEFI drivers are still not many.
Given the universality of UEFI systems on the AMD64 ecosystem and the unique ability to monitor, attack and protect the system throughout operating system startup on bare-metal systems, the authors believe that having the understanding and being able to author this type of hypervisors are valuable for research.
