How to repeat - download NetBSD-7.0-amd64.iso, then try this:
======================================================================
truncate -s8G netbsd.img
cat > netbsd.map << EOF
(hd0) netbsd.img
(cd0) NetBSD-7.0-amd64.iso
EOF
cat > netbsd.grub << EOF
knetbsd -h -r cd0a /netbsd
boot
EOF
sudo grub-bhyve -r cd0 -m netbsd.map -M 1024 netbsd < netbsd.grub
sudo bhyve -c 1 -m 1024M -H -P -A -W -w \
-l com1,stdio \
-s 0:0,hostbridge \
-s 1:0,lpc \
-s 2:0,virtio-net,tap0 \
-s 3,ahci-cd,NetBSD-7.0-amd64.iso \
-s 4,virtio-blk,netbsd.img netbsd
======================================================================
You'll get something similar to this:
root on cd0a dumps on cd0b
root file system type: cd9660
warning: no /dev/console
vm exit[0]
