Description Gordon Watson 2017-09-01 18:27:33 UTC

Description of problem:

If 'run_on_vds' in the vm_dynamic table in the RHV database contains a host id, but the VM is actually down, the engine will report the following;

- engine.log;

2017-08-31 07:43:23,615+05 INFO  [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (DefaultQuartzScheduler1) [] VM '6be6956f-b8b8-4a33-bb37-30334702b8b9'(cdvpgweb03) is running in db and not running on VDS 'e31634bf-d4a0-47e8-ba81-d49c280acaa3'(dch12bl13.cbec.gov.in)

They are not normal either way, but the host was responding, actually.
We should deal with the exception more gracefully, no matter how it happened (it may be restore from a backup)

Comment 5 Michal Skrivanek 2017-09-08 06:17:56 UTC

do we want also a 4.1 backport of https://gerrit.ovirt.org/#/c/81560/ ?
