The staging setup is optimized to run in vagrant containers to perform tests before applying major modifications to
production system. However, there are several pecularities to take care of
  - Vagrant uses NAT networking on eth0 (mandatory) and generates the same IP on all nodes. This confuses the OpenShift.
  As a solution: Customize NAT IPs and remove the default route on eth0 (configure standard dhcp on the second public interface)
