Public bug reported:

   Evacuate provide a way to recover instance from a failed compute node,
    compute manager changes instance's host and node name with target host
    before do real action '_rebuild_default_impl', we didn't catch exception
    from _rebuild_default_impl, any evacuate failure leaves instance's host
    and node name as target host's.  The worse thing is when restart the original failure node
   it check instance's host and  destory them in original  node.   We need recover instance's
   attributes host and node.
