Installed RDO Grizzly on RHEL 6.4 running in a VM on top of Fedora 19 using kvm Even with no nested VMs running inside of the allinone node, and just the core services running, I'm seeing CPU spikes every second. Basically CPU utilization reported by top goes from 2% to 60% and back to 2% or so about every second. Anyone have any idea if this is expected for an idle system? Perry
