Aaron, I hit that problem again, related to "MultipleAgentFoundByTypeHost" error message...
Sometimes the 'neutron-openvswitch-agent' (or `DHCP agent` too) gets duplicated, look: root@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.
