Good morning,
First - thanks for the instructions on WW4 and KVM!! I'm gald someone did this.
I followed the directions in your medium.com article (https://medium.com/@panda1100/warewulf-v4-sandboxing-environment-on-kvm-using-vagrant-f0e23fc1ce52) on an Ubuntu 20.04 system. I ran into a few errors.
$ vagrant plugin install vagrant-libvirt

Is this a problem? (I was able to go to the next steps)
vagrant up I got the following errors at the very end: server: 47 files removed

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
I'm not sure of the error and if it needs correcting or it can ignored.

I don't know how to fix this when the compute nodes are brought up (I could always add them them manually.
Than you for your help!!
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! :)
