[libvirt] [PATCH] support offline migration
by liguang 11 Sep '12

11 Sep '12

original migration did not aware of offline case so, add code to support offline migration quietly (did not disturb original migration) by pass VIR_MIGRATE_OFFLINE flag to migration APIs if only the domain is really inactive, and migration process will not puzzled by domain offline and exit unexpectedly. these changes did not take care of disk images the domain required, for them could be transferred by other APIs as suggested, then VIR_MIGRATE_OFFLINE should not combined with VIR_MIGRATE_NON_SHARED_*. so, this migration result is just make domain definition alive at target side.
