It probably would for this specific case, but my final goal is to be able
to write systemtap tracing scripts that can cross the entire virtualization
stack from virt-manager (python), through libvirt & libvirtd, down to qemu,
kvm and the kernel. Being able to collect data this way will be very useful
because it avoids the need to correlate & re-order data from multiple
application specific log files / trace files which is what we currently
do for most debugging.

Daniel
