please attach vdsm logs, ideally in debug From which host do you need the logs? any host which talks to this engine and triggers the err seems the list is reported wrongly once guest agent stops reporting data reporduced by running ovirt-ga to get appsList [...] and then stop it while VM is still running, you get [[...]] which breaks engine assumption This is not a blocker nor an exception, yet it is targeted for 4.2.3? it' minor, but raising a lot of false alarms. Same for the exception on vdsm side about onLibvirtLifecycleEvent. If they can make it in in time then they should vdsm patch ready to merge if exception flag approved Verified with: vdsm-4.20.31-1.el7ev.x86_64
Steps to reproduce on vdsm-4.20.27.1-1.el7ev.x86_64:
1. start vm with guest agent.
2. On the vm stop the GA service (systemctl stop ovirt-guest-agent.service)
3. In this point it is required to wait for few min till engine tries to update info on GA. (in my case ~3min)
4. Verify engine log:
2018-06-18 20:47:01,678+03 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (EE-ManagedThreadFactory-engineScheduled-Thread-47) [] Failed to convert app: [[Ljava.lang.Object;] is not a string
5. Get vm stats on the host (appslist is in double list [[...]]):
vdsm-client VM getStats vmID='{vm_id}' | grep appsList -A 6
"appsList": [
[
"kernel-3.10.0-693.11.1.el7",
"ovirt-guest-agent-common-1.0.14-3.el7ev",
"kernel-3.10.0-693.el7"
]
],
Result: Bug is no longer present in vdsm-4.20.31-1.el7ev.x86_64, resolution - Verified.
