Packstack does not handle interface names (CONFIG_NEUTRON_OVS_TUNNEL_IF, etc) containing "." or "-"

[Lars Kellogg-Stedman]

Given a setting such as:

  CONFIG_NEUTRON_OVS_TUNNEL_IF=eth0.212

packstack will generate a manifest that includes:

   $localip = $ipaddress_eth0.212

...which is an invalid variable name and will cause Puppet to fail with an error.

Simple replacing "." with "_" in interface name works for me. That's probably related to Facter (Puppet system config report tool) doing the same substitution.

For example replace

CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1.10

with

CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1_10
