[-- Attachment #1 --] Hello Corvin and all on this thread, Last time I've searched for docs and manuals on how to properly setup graphics passtru in bhyve, documentation was very fragmented. Is there a a wiki page or a place where docs are placed so we can access? If not, we could start a new thread on virtualization@ to start gathering all we can get, so a wiki or a complete manual could be made and incorporated in our handbook. Thanks all!
