    Send events to all relevant hosts if migrating
    
    Previously, external events were sent to the instance object's host
    field. This patch fixes the external event dispatching to check for
    migration. If an instance is being migrated, the source and
    destination compute are added to the set of hosts to which the event
    is sent.

Title:
  Evacuation fails with VirtualInterfaceCreateException

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description:

  With Neutron, evacuating an instance results in a
  VirtualInterfaceCreateException and the evacuation fails.

  Steps to reproduce:

  1. Boot a VM with a Neutron NIC.
  2. Cause the underlying host to be down, for example by stopping the compute service.
  3. Evacuate the VM.
  4. The evacuation will fail because the destination compute host waits for a network-vif-plugged event from Neutron, which it never received because Nova sends the event to the source compute.

  Environment: Neutron, KVM
