Good evening,
I am running oVirt 3.
I am not sure if the source of the problem is oVirt or KVM/qemu but 
the machines run really slow since some days ago. There are some 
warnings regarding iscsi storage latency in the oVirt portal but the 
behaviour is also present with NFS storage.
There are no visible errors either in engine.log or vdsm.log. 
Var/log/messages in the node shows over and over:
/usr/sbin/irqbalance: Load average increasing, re-enabling all
    cpus for irq balancing
and, after a while, waits in the node rise over 50%. It finally leads 
to a disconnection of the SPM node and a non-operational state.
Has anyone any ideas why this happens?
Regards,
Jose Garcia
