Yes any patches and testing here are appreciated. I thought I had
already published the py3 branch, but apparently not, so here it is now:

https://github.com/virt-manager/virt-manager/tree/py3

I'd like to keep all python3 specific patches there until we are ready
to make the switch. Some patches in that branch can still safely go to
master as they are py2 compatible, like the floor division patch.

My thoughts were do another release (or maybe two) of py2 virt-manager,
then commit the py3 branch to master and go from there.

I'm not really interested in keeping py2 support unless there's a very
good reason. While we maintain both it will double the testing time for
devs and there be compat imports sprayed across multiple files that will
be removed soon after. The actual inline code changes that are python3
specific aren't hugely invasive so I think it will be doable to handle
backports from latest py3 virt-manager to old py2 codebases.

Thanks,
