Title:
  few VMs fail to get ip address in devstack

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  I am running Juno int code on multi node devstack environment. I am
  trying to boot 10 VMs in each different network. If so, few VMs, will
  fail to boot. If i delete & recreate  a VM in the same network, it
  will fail to get the ip address.

  Here are the steps followed to hit this issue

  1. Create a network
  2. Create a subnet
  3. Create a distributed router. Add the subnet to this DVR
  4. Boot a VM.
  5. Follow the steps 1-4 for 9 more VMs.
  6. In this case, few VMs will not get the ip address. 
  7. I see that dhcp request is not reaching the NN. Please note that few more VMs hosted on the same CN are getting the ip address.

  On both Openstack Controller & Compute node logs does not show any
  Errors.
