Easily missed, good work. My grep for similar references to Python versions we don't support found a few 2.x, x < 7. Not this patch's problem, of course, but let me show them anyway: * scripts/qapi/common.py # re.subn() lacks flags support before Python 2.7, use re.compile() I'll clean this up. * tests/image-fuzzer/ docs/image-fuzzer.txt "Fuzzer requirements" item "17. Should be compatible with python version 2.4-2.7". Stefan, does the fuzzer need porting to Python 3? Two spots in the code are marked as 2.4 work-arounds: tests/image-fuzzer/qcow2/fuzz.py: in Python 2.4 tests/image-fuzzer/runner.py: # Python 2.4 doesn't support 'finally' and 'except' in the same 'try' Grep also found tests/vm/netbsd and tests/vm/openbsd pass --python=python2.7 to configure. Eduardo, should they be upgraded to a suitable version of Python 3? Possibly in your "[PATCH] Deprecate Python 2 support"? If yes, then https://wiki.qemu.org/Hosts/BSD also needs an update.
