The cpuTime of a VM reported by kvm72 is ok (real seconds ) while that reported by kvm-84 is not. Are you aware of this . Did you talk to kvm and was it fixed in latest kvm releases since 84 ? I access cpuTime via libvirt . (same version in both cases) . thanks Zvi Dubitzky Virtualization and System Architecture Email:dubi@il.ibm.com IBM Haifa Research Laboratory Phone: +972-4-8296182 Haifa, 31905, ISRAEL
