Aaron,

I hit that problem again, related to "MultipleAgentFoundByTypeHost" error
message...

Sometimes the 'neutron-openvswitch-agent' (or `DHCP agent` too) gets
duplicated, look:

root at havabuntu-13:~# neutron agent-list
+--------------------------------------+--------------------+--------------+-------+----------------+
| id                                   | agent_type         | host
| alive | admin_state_up |
+--------------------------------------+--------------------+--------------+-------+----------------+
| 1c7eec73-2a1a-47b2-b66e-4ecefacfcb7c | Open vSwitch agent | havabuntu-13
| xxx   | True           |
| 2d2e787a-06e1-483c-a0e4-c837bb38dc95 | Open vSwitch agent | havabuntu-13
| xxx   | True           |
| 58351edd-449e-4dd4-b864-0fb2614703f5 | DHCP agent         | havabuntu-13
| :-)   | True           |
+--------------------------------------+--------------------+--------------+-------+----------------+

I think I know what I'm doing to hit this, I'm trying to disable Namespace,
just for tests, and I ended up duplicating the Open vSwitch agent...

I'll make more tests to make sure but, I just noted that, after changing
the entries "allow_overlap_ips to false" and "use_namespaces to false",
somehow the agent gets duplicated.

I'll try to isolate it, and then, I'll write a small easy-to-follow
procedure to reproduce the problem, if desired.

Best,
Thiago
