Bug#1012462: vagrant-libvirt fails to bring up VM, errors out on private network

[Gabriel Filion]

Oohh .. I think I just found my issue, and it doesn't seem to be related 
to a bug in the software, but rather in my Vagrantfile.

from what I can see the variable that's used as the IP address for the 
private network is not getting me the value that it should.

so now I plunge into ruby debugging. I'll close this bug report since 
it's not linked to the package.

sorry for the noise about this.
