You can run it as:
$ qemu-system-x86_64 -enable-kvm -machine none -monitor stdio -qmp unix:/tmp/qmp,server,nowait -nographic
Then:
$ ./scripts/qmp/qmp-shell /tmp/qmp

2to3 output on QEMU source tree
So, most of the 2to3 fixes give false positives, but some fixers give some useful pointers:
'2to3 -f print' gives us this:
