Having fun with libvirt and qemu

I've been having some fun dealing with libvirt and qemu. qemu is the basic hypervisor that creates a virtual environment for execution and libvirt is the overall management library. libvirt has several checks built in to valid qemu and every-time, qemu changes (major version), libvirt fails or the default configuration needs tweaking (XML file).

Both are great projects, it is interesting to understand their architecture (which of course is way deeper than this post :))
