Thanks!

But I'm not clear that what the language binding means? What the relationship between they? Is that the code from https://libvirt.org/sources/ can be replaced completely by the code from https://libvirt.org/sources/python?

Language bindings are the means through which libvirt, which is implemented in C, can be used from non-C languages such as Python. It's basically a bunch of glue code that allows Python code to call into C code. In order to use libvirt from Python, you need to have *both* libvirt itself *and* the Python bindings installed on the system: libvirt-python doesn't replace libvirt, and in fact can't work at all unless the C library is available as well. -- Andrea Bolognani / Red Hat / Virtualization
