Open Stack

Hi.  I am trying to use multi_host to eliminate the "controller" hosts 
as a single point of failure.

I followed the steps at 
http://docs.openstack.org/essex/openstack-compute/admin/content/existing-ha-networking-options.html 
and added thse options to the end of nova.conf. Now the guests have no 
connectivity to the outside world at all. (Running on ubuntu 12.04 using 
packages.)

Controller:
--multi_host=True
--enabled_apis=ec2,osapi_compute,osapi_volume,metadata

Compute nodes:
--multi_host=True
--enabled_apis=metadata

I also tried changing the routing_source_ip option on each compute node 
to it's own ip address but it makes no difference.
--routing_source_ip=10.10.20.11X

What am I missing?
