    Installing OpenBSD in a bhyve VM under FreeNAS


Create a zvol for your OpenBSD VM
Add a VM with UEFI boot
Change NIC to VIRTIO
Add the zvol you created as a VIRTIO disk
Inspect HTML source for the row for the VM, look for dgrid_vm-row-# where the # is the ID

or subtract 5900 from the VNC Port
or use the sqlite3 command below
in new versions of FreeNAS it's listed in the GUI.


remove VNC device

you won't need it
I guess you can keep it, but you can't install OpenBSD over it


Install from a local image


Connect to a shell


Download an OpenBSD miniroot install image
  # fetch https://ftp.openbsd.org/pub/OpenBSD/snapshots/amd64/miniroot62.fs


dd it to the zvol you created
  # dd if=./miniroot62.fs of=/dev/zvol/ztank/vm_images/test bs=1M


make sure this is your zvol


figure out the VM ID for your OpenBSD VM (if you didn't earlier)
  # sqlite3 /data/freenas-v1.db 'SELECT id, name FROM vm_vm'


connect to the nmdm virtual console.
  # cu -l /dev/nmdm3B


where 3 is the id for your OpenBSD VM
I didn't find documentation about the fact that FreeNAS enables this serial console anywhere but the source.


Start the VM by clicking start in the UI.


On the console boot> prompt set tty com0

and do the install making sure to set console to com0 and choose GPT disk partitioning


Install over the network

On the server hosting the install data:


Enable httpd and create an install.conf in /var/www/htdocs


Enable tftpd and download some files to /tftpboot:
  cd /tftpboot
  ftp https://ftp.openbsd.org/pub/OpenBSD/snapshots/amd64/{BOOTX64.EFI,bsd.rd}
  ln -s BOOTX64.EFI auto_install
  mkdir etc
  echo "set tty com0\nset image bsd.rd" > etc/boot.conf


You need a very current BOOTX64.EFI with patrick@'s patch that got committed on 2017-11-25.


On your DHCP server, set up the entry for your bhyve VM:


Finding the MAC is left as an exercise for the reader


Although I watched my dhcp server logs the first time I booted the VM.


But, before you remove the VNC device above you can connect to the EFI console there and exit from the shell and find the MAC in the menus.
  host test {
      option host-name "test";
      hardware ethernet 00:XX:XX:XX:XX:30;
      fixed-address 192.168.0.71;
      next-server 192.168.0.50; # This is the IP of the install server
      filename "auto_install";
  }


You can connect to the console on /dev/nmdm3B as described above to do debugging, but once it works that is optional.
But, when you start the VM it should fall back to "EFI Network" and boot from the network.
Your OpenBSD install should now be working.
