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:
