During downtimes, such as when hypervisor restarts, if you run a docker-dependent command, instead of getting “Not up yet” or “docker down”, I see “ERROR: Couldn’t connect to Docker daemon - you might need to run `docker-machine start default`.”

But docker-machine isn’t used in the hypervisor, right?

It gives me back an error: `Docker machine "default" does not exist. Use "docker-machine ls" to list machines. Use "docker-machine create" to add a new one.`
