In the Nova configuration, the 'my_ip' setting is the IP address the host

To correct this part a bit, Nova sets up ibtables rules for the metadata
service using the 'metadata_host' config setting which defaults to
$my_ip. There are a handful of config settings that default to $my_ip if
not specified. But, I think since 'my_ip' is defined as the host's IP on
the management network, we anyway need to give users the ability to set
it if they are in a situation where their host has more than one IP.
1) puppet-nova and add the parameter in the class that requires it.
Which Nova service does require it? If all, add the param in init.pp
otherwise in the service class. Ping us on #puppet-openstack if you
need any help, in the case you're not familiar with Puppet. We'll
enjoy to help.
For the metadata service iptables issue, it's only needed by the Nova
metadata API service. But, I wonder if it should be able to be set for
any Nova service since any Nova service could make use of the 'my_ip'
setting and 'my_ip' is defined as "IP on the management network." I'm
not sure. I need to do a full audit on where all it's used directly and
indirectly.
Thank you all for the helpful replies!
