We have DUET running as a coreboot payload with a small coreboot
specific PE payload loader.
DUET is, however, not an emulator, it is executing much of the same code
as all other TianoCore based UEFI implementations.
It is possible to boot an OS just fine with DUET.
Can you explain what you think would be more direct about OVMF than
about DUET? As far as I understand it's another build target of EDK2 but
besides that shares exactly the same design and even 99% of the code.
