Title:
  nova evacuate fails with neutron

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) icehouse series:
  Fix Released

Bug description:
  When I deploy nova with a shared storage and with
  neutron/ML2/linuxbridge, I have an error when I want to to use "nova
  evacuate"

  command : 
  # nova evacuate 1fa486f3-259c-4e1e-ae82-8b52606f1efd devstack2 --on-shared-storage

  here are the logs on the compute node (devstack2) which will host the
  VM after the evacuation:
