Hi!
Thanks for the advice, running it like this:
bhyve -c 2 -a -A -m 1024 -M 4096 -I -H -g 0 -s 0:0,hostbridge -s
1:0,virtio-net,tap3 -s 2:0,virtio-blk,/dev/zvol/z0/bhyve/vm3 -S
31,uart,stdio vm3 < /dev/null - really allows me to send it to background!

But, if i modify -S 31,uart,stdio to -S 31,uart - 9.1 guest still won`t
boot - bhyve process is in [vmidle] state, and there is no activity
inside vm. I don`t know if this is important, reporting it just in case :)

Thank you.
