I see some work was started a few years ago (e.g. https://reviews.freebsd.org/D26976, https://bhyvecon.org/bhyvecon2016-Mihai.pdf). It seems to have been abandoned or at least stalled. > > I may be able to help. It's not a project I can take on myself. Porting bhyve to arm has been one of the longest running UPB projects. You can find more info on the history here ... https://wiki.freebsd.org/DevSummit/202303?action=AttachFile&do=view&target=Presentation+-+bhyvecon.pdf Your best bet is probably to take a look a the following review opened by Andrew Turner late last year. His work is based on the original port by the UPB team ... https://reviews.freebsd.org/D37428 I can't speak to the current state of this work. From what I recall, there were several attempts made by UPB to collaborate, but they failed to get a response. Perhaps he/they can chime in here with more detail. -Matthew
