You have to calculate the percentage utilization yourself by making repeated queries to the cpu status calls, and tracking how the cumulative usage grows over time. You may want to look at the source code of virt-top for ideas on how to do it. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
