Hi, vmctl doesn't allow to boot VMs with only a CDROM. I see no reason for it and vmd already allows CDROM-only.
OK? Via https://twitter.com/wizardishungry/status/1032327323125727232 "Jon Williams @wizardishungry @reykfloeter Could you consider allowing booting ISO-only vms in 6.4? This is helpful for running container hosts (e.g. boot2docker)."
