You'll get a series of events emitted 1. On destination: VIR_DOMAIN_EVENT_STARTED + VIR_DOMAIN_EVENT_STARTED_MIGRATED 2. On source, if non-live migration: VIR_DOMAIN_EVENT_SUSPENDED + VIR_DOMAIN_EVENT_SUSPENDED_MIGRATED 3. On source, if completed VIR_DOMAIN_EVENT_STOPPED + VIR_DOMAIN_EVENT_STOPPED_MIGRATED 4. On source, if aborted & non-live VIR_DOMAIN_EVENT_RESUMED + VIR_DOMAIN_EVENT_RESUMED_MIGRATED 5. On destination, if successful VIR_DOMAIN_EVENT_RESUMED + VIR_DOMAIN_EVENT_RESUMED_MIGRATED 6. On destination if failed VIR_DOMAIN_EVENT_STOPPED + VIR_DOMAIN_EVENT_STOPPED_FAILED
