I'm having problem using the script with -k option.
qemu command line :
ExecStart=/usr/bin/qemu-system-x86_64 -daemonize -name %i,debug-threads=on -pidfile /run/qemu_%i.pid -monitor unix:/tmp/%i.sock,server,nowait,nodelay $args
args contain this smp definition: -smp sockets=1,cores=12,threads=1
(note: hyperthreading doesn't work on ryzen/qemu actual version so i'm sticking with single core/threads )
ExecStartPost=/bin/sh -c 'exec /usr/local/bin/qemu-affinity $MAINPID -p 0-1 -i *:0-1 -q 0-1 -w *:0-1 -k 4 5 6 7 8 9 10 11 12 13 14 15'

cpus from 4 to 15 are isolated through isolcpus parameter in kernel.
Journalctl :
Traceback (most recent call last):
lug 17 09:54:11 ryzensrv sh[9839]: File "/usr/local/bin/qemu-affinity", line 11, in

By default, running qemu-affinity on Linux Mint 19 gets a generic error:

Traceback (most recent call last):
  File "/usr/local/bin/qemu-affinity", line 7, in <module>
    from qemu_affinity import main
  File "/home/haruka/.local/lib/python2.7/site-packages/qemu_affinity.py", line 4, in <module>
    from pathlib import Path
ImportError: No module named pathlib

This is because python 2.7 is the default. qemu-affinity should check the version string before using it, and check for a python3 binary if the python version is not 3 already.

$ python --version
Python 2.7.15rc1
$ python3 --version
Python 3.6.5

However, even setting the opening line of the script to #!/usr/bin/python3 then we still get an error:

$ qemu-affinity --help
Traceback (most recent call last):
  File "/usr/local/bin/qemu-affinity", line 7, in <module>
    from qemu_affinity import main
ModuleNotFoundError: No module named 'qemu_affinity'

But I'm unsure as to why its throwing this error.
