[-- Attachment #1 --] --> I was about to attempt this myself. Are all the required patches present in 14.4 as well ? It would be nice if you can apply the Corvin patches for FreeBSD 15.x and tell if you get the error "bhyve: bootrom_alloc: vm_mmap_mapseg: Invalid argument". This will help to understand if there is a problem between Corvin's code and some component of FreeBSD 15.x or if it belongs only to me. Mario.
