OpenStack uses libvirt so you should take a look at the APIs available there instead of accessing QEMU directly: http://libvirt.org/html/libvirt-libvirt.html If you want to quickly explore what information is available, try running virt-manager(1) or virsh(1). They can report guest/host CPU utilization, memory usage, block I/O statistics, network I/O stats, etc. For help with libvirt, see: http://libvirt.org/contact.html Stefan
