Open Stack

Debugging further, I see the below entries
in /var/log/neutron/openvswitch-agent.log:

2014-06-20 11:08:02.954 5410 INFO neutron.api.v2.resource [-] create failed
(client error): No more IP addresses available on network
31956556-c540-4676-9cd4-e618a4f93fc8.
2014-06-20 11:08:02.955 5410 INFO neutron.wsgi [-] xxx.xxx.xxx.xxx - -
[20/Jun/2014 11:08:02] "POST /v2.0/ports.json HTTP/1.1" 409 360 0.117780

The network mentioned in the error log is a public network, and all ips
from that range has been assigned to vms already.

[root at localhost ~(keystone_admin)]# neutron net-list

+--------------------------------------+---------+---------------------------------------------------------+

However, shouldn't Openstack only care about the private network, and
assign a private ip and bring up the interface?

Also, how do I go about adding another public range which is already routed
to this Openstack server's public eth device? I tried to add the second
public ip range as another subnet inside net "public" (which in turn should
make Openstack realize that free ips are available) but it still fails with
the same error, and eth1 is not yet being created on the vm.

Please assist.
