Title:
  aborted: Failed to allocate the network(s), not rescheduling

Status in OpenStack Compute (nova):
  Expired

Bug description:

  controller nodes:
  con1  con2   con3 


  compute nodes:
  compute01

  oopenstack version: train

  
  There are no problems in the all-in-one test，Change to multi-node point to create a virtual machine and report the following error? The linuxbridge-agent on comput01 can create the vm network normally, but nova did not receive the message that the linuxbridge-agent creation is complete, resulting in a timeout error. I can also ignore this error by changing the nova.conf parameters. But this is not the right way to solve the problem
