Arvados

I was interested in running arvados locally.
I tried to follow the instructions to try out arvados here: https://doc.arvados.org/install/arvbox.html
I used vagrant with ubuntu/trusty64.
While running this command

./arvbox start localdemo

It gets to a point where it keeps printing the following and doesn't seem to be making any progress:

Waiting for keepstore0 keepstore1 keepproxy vm ...
Waiting for keepstore0 keepstore1 keepproxy vm ...
Waiting for keepstore0 keepstore1 keepproxy vm ...

I let it run for about an hour without any progress.

I tried to look at the services with the log command:
```
