The Vagrant-File seems to be broken.
1. I tried to "vagrant up centos64" which failed due to files that could not be downloaded during provisioning.
2. Saucy Images are no longer available and should be removed from Vagrantfile.
3. I guess it would be better to use sshfs instead of nfs for the shared folder due to the fact that a lot of people use encrypted home-directories these days which makes mounting the shared folder fail. You don't even get a proper errormessage for that.
I didn't check all resources refered to by either Vagrantfile or the puppet files but i guess there are even more broken links.
