Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have been 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.
Versions of Python available in our supported build platforms as of today, with optional versions available in parentheses: openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2) CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16) CentOS Stream 9: 3.9.13 Fedora 36: 3.10 Fedora 37: 3.11 Debian 11: 3.9.2 Alpine 3.14, 3.15: 3.9.16 Alpine 3.16, 3.17: 3.10.10 Ubuntu 20.04 LTS: 3.8.10 Ubuntu 22.04 LTS: 3.10.4 NetBSD 9.3: 3.9.13* FreeBSD 12.4: 3.9.16 FreeBSD 13.1: 3.9.16 OpenBSD 7.2: 3.9.16 Note: Our VM tests install 3.7 specifically for freebsd and netbsd; the default for "python" or "python3" in FreeBSD is 3.9.16. NetBSD does not appear to have a default meta-package, but offers several options, the lowest of which is 3.7.15. "python39" appears to be a pre-requisite to one of the other packages we request in tests/vm/netbsd. Since it is safe under our supported platform policy, bump our minimum supported version of Python to 3.7.
