Hello
I had the same problem ("Timeout waiting for vif plugging callback for instance"), and it can be caused by an invalid Neutron configuration. For me the solution was to fix a typo in /etc/neutron/plugins/ml2/ml2_conf.ini:
I replaced: firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIpTablesFirewallDriver
With: firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
But your problem can be caused by anything that prevents Neutron from working properly. To find the error, you could go to /var/log/neutron on the misbehaving node, and do:
tail -f *
And wait for errors to appear. My error was something like "Module OVSHybridIpTablesFirewallDriver doesn't exist", because of the typo.
