Public bug reported:

When nova evacuate or host-evacuate are used to recreate instances with
sriov ports the instances are allocated new device ids on the target and
neutron is updated accordingly.  However the network info data passed to
the driver spawn method is not updated and thus the instance tries to
use the device id they were allocated on the source node.  If a pre
existing instance is using that device id or no such device exists on
the target node then the instance will fail to start.
