OpenBSD vm troubles

I am not sure what it is that I am doing wrong, but I am unable to install
OpenBSD.

Here is how I am invoking the installer:
```
bhyve -A -D -H -P -S -u -w -c 8 -m 4G \
-s 0,hostbridge \
-s 3,ahci-hd,/usr/local/bhyve-vms/.iso/miniroot74.img \
-s 4,virtio-blk,/usr/local/bhyve-vms/OpenBSD/openbsd74.img \
-s 5,virtio-net,tap1 \
-s 8,hda,play=/dev/dsp,rec=/dev/dsp \
-s 20,virtio-rnd \
-s 29,fbuf,tcp=0.0.0.0:5901,w=1680,h=1050,wait \
-s 30,xhci,tablet \
-s 31,lpc -l com1,stdio \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \
openbsd74
```

I end up with:
```
probing: pc0 com0 com1 mem[640K 3049M 128K 16M 3M 1024M]
disk: hd0 hd1*
>> OpenBSD/amd64 BOOTX64 3.65

Turning timeout off.

```
Not sure what I need to do for the installer to run.

 In an Internet failure case, the #1 suspect is a constant: DNS.
"Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-)
