Hi,

thanks a lot for the cool setup you provided/described in your medium post and, of course, here on Github.
Setting up the Warewulf server works fine for me, but when I try to start the compute nodes afterward, I get the following error:

$ vagrant up n0001
Bringing machine 'n0001' up with 'virtualbox' provider...
There are errors in the configuration of this machine. Please fix
the following errors and try again:

vm:
* A box must be specified.

I have tested this behavior with Vagrant versions 2.3.4 and 2.2.19.

Any clue, what could be the issue?

Thanks! :)
