I'm using sysutils/vm-bhyve, not start bhyve manually.
From logs for this machine:
bhyve options: -c 1 -m 1024M -AHP -U d55d45d4-46e1-11e6-85e6-1c6f65d8653a
bhyve devices: -s 0,hostbridge -s 31,lpc -s 4:0,virtio-blk,/dev/zvol/data2g/vm/freebsd/disk0 -s 5:0,virtio-net,tap0,mac=58:9c:fc:0d:78:06
bhyve console: -l com1,/dev/nmdm0A
