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
