Answer 1

I assume that you have a network problem. Are you behind a proxy? Is it possible that it filters the connection to docker.io or blocks the docker user agent?

I installed the toolbox and ran your test. It works fine, here:

docker is configured to use the default machine with IP 192.168.99.101

Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
