hi experts:

I am a freshman of libvirt, I have got a domU's info like: libvirt.open, lookupByID, info.

But now I want to use libvirt to get a xen domU 's cpu usage ratio , how can I fulfill it ? I cannot find the API.

virNodeGetCPUStats shows the usage of the overall machine (Dom0 + DomU); and the new virDomainGetCPUStats is the API that was designed to give per-cpu usage of an individual DomU. However, no one has yet wired up the new API to work on xen (for that matter, the patches to wire it up to qemu-kvm are still waiting for me to review and apply them - I guess I'd better do that today). Patches welcome. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
