I can't access sage vertual machine from windows host by address `localhost:8000`.

[Wei, Huayi]

Hi, There

My windows is win 7. I import Sage-7.2.ova into virtualbox (version
5.1.4) with the default setting.

And I want to access the Sage-7.2 virtual machine, which has been
booted, from my host system by browser, for example, chrome.

I input `localhost:8000` into chrome, but I can't access the notebook.

Anyone ever got such problem? And How to fixed it?

Thanks

Huayi
