Recently we meet a strange issue between neutron-server and neutron-dhcp-agents. In a long run deployment, we just restart all neutron-servers, then we failed to boot VM. Yes, it is vif-plug-timeout!!! We noticed that the DHCP provisioningblock was not deleted.
Our operator gives the recover steps:
1. stop the network's scheduled dhcp-agents
2. delete the related Queues in rabbitMQ of these dhcp-agents
3. start dhcp-agents.

Then everythin will works fine.
So, do you have any idea about such issue?
