Good evening,<br>
<br>
I am running oVirt 3.<br>
<br>
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.<br>
<br>
There are no visible errors either in engine.log or vdsm.log.
Var/log/messages in the node shows over and over:<br>
<br>
<blockquote>/usr/sbin/irqbalance: Load average increasing,
re-enabling all cpus for irq balancing<br>
</blockquote>
<br>
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.<br>
<br>
Has anyone any ideas why this happens?<br>
<br>
Regards,<br>
<br>
