+I tried using a CentOS base box but the network config didn't work... the VMs didn't get the IP addresses from the Vagrantfile. Here is the error:
+
+ [controller] Configuring and enabling network interfaces...
+ The following SSH command responded with a non-zero exit status.
+ Vagrant assumes that this means the command failed!
+
+ /sbin/ifup eth1 2> /dev/null
+
+Other users of CentOS base boxes report similar problems here: https://github.com/mitchellh/vagrant/issues/997
