Pylint 2.16 adds a few new checks that cause the optional check-tox CI
job to fail.
1. The superfluous-parens check seems to be a bit more aggressive,
2. broad-exception-raised is new; it discourages "raise Exception".
Fix these minor issues and turn the lights green.

At the moment, we look for just "python3" and "python", which is good
enough almost all of the time. But ... if you are on a platform that
uses an older Python by default and only offers a newer Python as an
option, you'll have to specify --python=/usr/bin/foo every time.

The pipenv tool was nice in theory, but in practice it's just too hard
to update selectively, and it makes using it a pain. The qemu.qmp repo

so I'm backporting that change here to qemu.git.

If we begin requiring Python 3.7+, a few platforms are going to need to
install an additional Python interpreter package.
As a courtesy to the user, suggest the optional package they might need
to install. This will hopefully minimize any downtime caused by the

Python 3.6 is at end-of-life. libvirt-ci now supports overrides for
targets and package mappings, therefore QEMU can use newer versions
provided by CentOS 8 (Python 3.8) and OpenSUSE 15.3 (Python 3.9).
Packages that the distro does not provide are included in the image

Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have
begun dropping support for this version and it is becoming more
cumbersome to support. Avocado-framework and qemu.qmp each have their
own reasons for wanting to drop Python 3.6, but won't until QEMU does.

This is my take on John's patches to improve Python detection and to

Shorten a bit the description of what libvirt-ci does, the name of the

Once upon a time, "sphinx-build" on certain RPM platforms invoked

These days, none of our supported platforms utilize a 2.x version, so it
