Title:
  ML2 : hard reboot a VM after a compute crash

Status in neutron:
  Won't Fix
Status in openstack-manuals:
  Fix Released

Bug description:
  I run in multi node setup with ML2, L2-population and Linuxbridge MD,
  and vxlan TypeDriver.

  I start two compute-nodes, I launch a VM, and I shutdown the compute-
  node which host the VM.

  I use this process to relaunch the VM on the other compute-node :

  http://docs.openstack.org/trunk/openstack-
  ops/content/maintenance.html#totle_compute_node_failure

  Once the VM is launched on the other compute node, fdb entries and
  neighbouring entries are no more populated on the network-node nor on
  the compute node
