Solving boot2docker’s fail to start error

I’m putting this obvious solution up as I couldn’t see it anywhere
online.

If you try to start up boot2docker with boot2docker start and it
returns.

error in run: Failed to start machine "boot2docker-vm": exit status 1

Before destroying everything and wiping your ~/Virtualbox VMs folder,
try starting up Virtualbox and seeing if the vm simply hasn’t been
suspended due to an OSX suspend or shutdown.

1. Unpause the machine
2. Send a shutdown signal
3. Try boot2docker start again.

And that’s it, hope it works for you.
