[ovirt-users] VMs running in DB, but not in VDS

[SATHEESARAN]

Hello All,

I was powering off lot of VMs ( around 29 vms ) in one go, by selecting 
them all,
and 'power off' option.

While doing so, I see that 2 of the VMs are stuck in powering down state.

I see the following exception in engine.log
<snip>
2016-06-20 05:10:57,645 ERROR 
[org.ovirt.engine.core.vdsbroker.VmsMonitoring] 
(DefaultQuartzScheduler_Worker-53) [7f967349] Failed during vms 
monitoring on host host1.lab.eng.blr.redhat
.com error is: java.lang.ClassCastException

java.lang.ClassCastException
</snip>

and also the following error messages
