Maybe use dl.fedoraproject.org instead of a mirror server?

As the KNOWN_DISTROS grows, more loosely methods will be created in the 
avocado_qemu/__init__.py file.

I refactored the code so that KNOWN_DISTROS and related methods are 
packaged in a class. See in:

https://github.com/wainersm/qemu/tree/eauger_avocado-qemu-v3-refactor

Maybe you could incorporate that in your series? Otherwise I can send as 
a follow up series. Whatever you prefer.

Thanks!
