Explicitly set VM state to paused after migration completes
In v3 migration, once migration is completed, the VM needs to be left in a paused state until after Finish3 has been executed on the target. Only then will the VM be killed off. When using non-JSON QEMU monitor though, we don't receive any 'STOP' event from QEMU, so we need to manually set our state offline & thus release lock manager leases. It doesn't hurt to run this on the JSON case too, just in case the event gets lost somehow * src/qemu/qemu_migration.c: Explicitly set VM state to paused when migration completes
