Bug description:
Most users expect that if a live migration fails but the instance is
fully recovered, it shouldn't enter 'error' state. Setting the
migration status to 'error' should be enough. This simplifies
debugging, making it clear that the instance dosn't have to be
manually recovered.
This patch changed this behavior, indirectly affecting the Hyper-V
driver, which propagates migration errors:
Idfdce9e7dd8106af01db0358ada15737cb846395
When using the Hyper-V driver, instances enter error state even after
successful recoveries. We may copy the Libvirt driver behavior and
avoid propagating exceptions in this case.
