Using Docker/Podman to run a container with an old version of Linux distribution that support Python 2.7 could be the most power-saving option (e.g. Debian Bullseye a.k.a. oldstable.) Using a Docker means no hypervisor required and application running in a container runs at near-bear-metal speed thanks to kernel support. Additionally you got some level of isolation from your host so that some of the unsupported old Python 2 vulnerabilities are under control within your container (not bullet-proof, but still something.) -- Regards, Xiyue Deng
