Hi,
I'm taking my first steps in using bhyve, and the first showstopper
seems to be that using '-l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd' gets me immediate
vm exit with exit_reason being 48 (EPT violation).
Relevant part of dmesg:

Simplified invocation line (I tried with a lot more options initially,
but this seems to get the same):
