This all appears to work. I built my own libvirt with the three remaining patches and was able to read pCPU information for a running domain. I have pushed the required bits upstream in ocaml-libvirt and virt-top: http://git.annexia.org/?p=ocaml-libvirt.git;a=summary http://git.annexia.org/?p=virt-top.git;a=summary (ocaml-libvirt >= 0.6.1.1 and virt-top >= 1.0.7) Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
