Public bug reported:
I hit an extra exception during a failed live migration rollback. This
exception occurred on the destination node. This bug is not about the
reason for the failed migration, but for the failure in the rollback.
The exception:

In compute manager.remove_volume_connection, this line calls driver_detach:

This is driver_detach in block_device.DriverVolumeBlockDevice:
def driver_detach(self, context, instance, volume_api, virt_driver):
The connector seems to be the culprit.
