Red Hat Bugzilla – Bug 965525
Inaccurate message displayed after VM live migration finishes
Last modified: 2015-09-22 09:09 EDT
Description of problem:
Upon live migration of a VM, the Event log reports
"VM <vm_name> is down. Exit Message: Migration succeeded"
Version-Release number of selected component (if applicable):
Live migrating any VM gives the same message. Appears to be move prevalent when live-migrating multiple VM concurrently, for instance when placing a loaded hypervisor into maintenance mode.
Steps to Reproduce:
Confusing message appears, probably from source host reporting that the VM is down.
The message should note if the migration succeeded or not, not from the source host saying that the VM is down.
The message comes from the source host reporting that he VM is down, which is technically correct, but irrelevant.
there seems to be a race in setDownStatus, it first set status to Down and only after that actually stop the statistics thread. If you're unlucky the stats get sent in the meantime
vdsm logs would help to confirm
After investigation, we've agreed on moving this bug to engine, as from vdsm's point of view the status of migrated VM is simply poweroff/nonexistant and no further information should be sent. Engine should supress the message and focus on success of migration on destination host.

Does the message is error message or a regular event log?
we want to suppress this to not alarm users…it's a normal case and you get the migration succeeded event afterwards anyway
