looks like a race between getallvmstats reporting VM as Down (statusTime: 4296271980) being processed, while there is a Down/MigrationSucceeded event arriving (with notify_time 4296273170) at about the same time
Unfortunately the vdsm.log is not in DEBUG level so there’s very little information as to why and what exactly did it send out.
@infra - can you enable debug log level for vdsm by default?

It does look like a race to me - does it reproduce?
