When migrating a domain from src to dst, it first appears 'suspended' at the dst. When it's 'running', higher-level management can tell that migration is done.
However, when bugzilla.redhat.com/519204 is fixed, I can no longer count on that - migrated domain may still be suspended at the destination.
So how can I tell, at the destination, that migration is over? I could add higher-level communication from src to dst, but I am reluctant to add another failure mode. I'd rather have libvirt tell me, "hey migration is done".
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
oh, so the 'detail' parameter is not just an ornament.. Thanks!
