I have the same ERROR messages in Neutron 11.0.3.

When I'm trying to spawn 100 VMs at once, several of them ends in ERROR state.

For every VM in ERROR state I have in nova-compute logs:

2018-03-22 17:06:26.148 7 WARNING nova.virt.libvirt.driver [req-ba580644-629a-4bec-afce-9d92b50c10de 726c3421bafc468ab0e2db45fc18f1e7 7ff6681fd929452d885184e39b1ba75d - default default] [instance: 910d4ef1-fcc5-46a6-8f87-c029e45059fd] Timeout waiting for vif plugging callback for instance with vm_state building and task_state spawning.: Timeout: 300 seconds

The interesting thing is that ERROR state is always on VMs spawned one after another, for example for VMs from test-11 to test-16. So it looks like it didn't worked only in one point of time.

In neutron-server logs I have ERRORs:
