I met similar issue recently, with share storage ceph backend.
'ImageBusy: error removing image' just was another exception when
clean up instance on target host after evacuate failure . The image
is used by the original instance from ceph side, so ceph think it was
used . In normal evacuate workflow we don't need clean up imag ,so
the root cause is why the evacuate failure .In my test env , I hit
the bug https://bugs.launchpad.net/neutron/+bug/1357476,
