What is the use of --routing_source_ip

This flag is used for specifying the source IP address to be used in source NAT.
It should be specified only when the VlanManager is being used, and it is by default initialized to the value of the my_ip flag (documented).

As concerns information for undocumented flags, I don't know any place where you can find that information. One way of finding it is doing a search for the flag name in the source code and then read the description associated with the flags.DEFINE_xxx statement.

Salvatore, is Openstack's official documentation [1] then incorrect when it shows "routing_source_ip" used with FlatDHCPManager?

FlatDHCPManager uses it too.

I apologise for the incorrect comment previously posted to this question.
My comment was pre-cactus (March 2011).
