To fix:

  qemu-test.test_pylint "/home/alex/lsrc/qemu.git/tests/functional/arm/test_integratorcp.py:83: I1101: Module 'cv2' has no 'imread' member, but source is unavailable. Consider adding this module to extension-pkg-allow-list if you want to perform analysis based on run-time introspection of living objects. (c-extension-no-member)"

Manually running python3 showed I could indeed import cv2 and call
those functions.

Which pylint version are you using? I don't get this with my pylint here 
(version 4.0.4)...

Ok ... thinking about it, I think it would be better to rather add 
"c-extension-no-member" to the "disable" list in our pylintrc instead, 
otherwise this will likely pop up in other spots as well and then we have to 
constantly extend the list each time which sounds cumbersome. Could you 
please try whether adding "c-extension-no-member" to the disable=... section 
silences the warning for you?

  Thanks,
   Thomas
