[ovirt-users] WARN VdsBroker

[Vrgotic, Marko]

Dear Roy,

Thank you. I noticed after completing the upgrade of the engine, and update of the hypervisors, that one hypervisor could not enter Maintenance state, as it was showing to be still hosting one VM. However, I could not find which one, the list showing hypervisor VMs was empty.
I was able to connect the relation between WARN message and “invisible” VM, and its solved now.

I will definitely look more into vdsm, as it is new to me, thank you, this information is valuable.

I think we can close this case.

Kind regards,
Marko Vrgotic

Every VDSM(host) reports the application list per installed vm, every time the engine asks for the vm statistics. The list probably contains an illegal value or we fail to convert it , anyhow it doesn't interfere with the rest of the monitoring process.  Please share the output of this command from one of your hosts that have running vms:
vdsm-client Host getAllVmStats

Hi oVirt community,
