Atomic Host - HyperV Login

So.. I just downloaded the hyper-v image to give this a shot. I created the VM successfully and launched it and now.. I have no idea how to log in. I've checked all the documentation I can find and there is no default user/password for this. Since I can't modify the cloud-config, I can't add my own user.

Where do I go from here? Am I missing something?

Thanks!
