BTW, we just hit a problem with macOS homebrew changing python to point to

a py3 binary and that showed other libvirt failures. In particular the ESX
code generator is broken under py2. I wouldn't be surprised if more of our
python scripts are also broken. So I think we need a general work item to
fix py3 compat for libvirt - if someone wants to work on it for the 4.2.0
release....

I noticed that in there are only 7 python files which need to be made compatible with Py3.

The 2to3 tool shows some obvious fixes. (e.g. print statement, dict.items(), etc.)
In addition, this documentation very helpful: http://www.diveintopython3.net/porting-code-to-python-3-with-2to3.html
