ubuntu@monitor:~$ sudo route del default gw 10.10.11.129<br>
ubuntu@monitor:~$ sudo route add default gw 10.10.11.112<br>

But the default gateway is assigned by DHCP - so how can I change
the default gateway that nova-network assigns on each compute node?<br>

am trying to use multi_host to eliminate the "controller" hosts as

I followed the steps at
<a class="moz-txt-link-freetext" href="http://docs.openstack.org/essex/openstack-compute/admin/content/existing-ha-networking-options.html">http://docs.openstack.org/essex/openstack-compute/admin/content/existing-ha-networking-options.html</a>
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.)
<br>
<br>
Controller:
<br>
--multi_host=True
<br>
--enabled_apis=ec2,osapi_compute,osapi_volume,metadata
<br>
<br>
Compute nodes:
<br>
--multi_host=True
<br>
--enabled_apis=metadata
<br>
<br>
I also tried changing the routing_source_ip option on each compute
node to it's own ip address but it makes no difference.
<br>
--routing_source_ip=10.10.20.11X
<br>
<br>
What am I missing?
