Tested v4.5.0.1295.gf41543 snapshot. It boots fine with virtio-blk and
virtio-net. However, as soon one or more CPU is added together with AHCI
enabled DragonFly hangs just before "Mounting root from ...". Try adding
the following options to the quoted command line.

  -c 2 -s 3,ahci-cd,/dev/md0

--
Discovered with vm-bhyve which passes -s 3:0,ahci-cd,null.iso to UEFI VMs.
