I have ubuntu 14.04.5 installed as guest os in virtualbox 5.0.26 running on windows 10. I am not aware of any issues with the ubuntu installation, it seems to run fine and has a bridged internet connection so gets its own ip. The windows host is not behind a proxy.
I have installed docker following the directions on docker docs for linux. The installation goes fine without any errors and the docker daemon starts ok. Here is the docker info:

The ubuntu vm can see the internet fine and can access hub.docker.com from a browser.
However, when I run the simple hello-world test the daemon hangs
root@ubuntu-z9:~# docker run hello-world
Unable to find image 'hello-world:latest' locally
with a timeout.
I can run docker-machine without any issues on the host windows 10 machine so I believe the issue lies in my setup of the ubuntu machine in virtualbox and docker.
Here is the logging output from the daemon on the ubuntu guest when I run it in debug mode:
$ docker run hello-world

Any suggestions on a way forward to diagnose or fix the issue?
Many thanks.
(This is a total newbie question so I also posted it on stackoverflow.)
