After some digging, it seems that the ip lookup fails, because eth1 is named enp0s8 my environment.
This also affects the other ip addresses.

Ok, this affects VirtualBox which uses the "predictable if name schema". Parallels does not for some reason.

Workaround: Edit .puppet/hieradata/common.yaml and replace eth1 with enp0s8.
I am still not convinced if enp0s8 always stays the same. There are some guides on the net which allow to disable predictable names and just use eth0/eth1. Still, hiera lookup with a fallback would be better.

Ok, fuck it. You cannot reliably determine the secondary interface. Either you attempt to extract that with hiera lookup(), modify hiera to support regexp on key/values. Or you'll go by the route of writing a custom fact which attempts to extract the secondary ip address.
Nothing which works reliably, therefore hieradata gets node specific ip addresses configured like anything else (the distributed boxes already override common.yaml with node specific data). This is how Puppet works, Vagrant is just a bonus on top for the host only bridge.
