I'm pretty sure it does. In `cmds.go` on line 91 we have

```Go
	logf("Setting VM host-only networking")
	hostIFName, err := getHostOnlyNetworkInterface()
	if err != nil {
		logf("Failed to create host-only network interface: %s", err)
		return 1
	}
```

So any error returned will be printed there. Or did I misunderstand what you want? Please let me know! :)
