Python is not exactly my forte, but the above makes sense to me and it stood up to some testing across all platforms supported by libvirt, so Reviewed-by: Andrea Bolognani <abologna@redhat.com> One nit is that the comment above the code doesn't IMHO describe the situation properly: I would have worded it along the lines of # Python < 3.4.4 doesn't have 'ensure_future', so we have to fall # back to 'async'; however, since 'async' is a reserved keyword # in Python >= 3.7, we can't perform a straightforward import and # we have to resort to getattr() instead I leave it up to you whether or not you want to reword the comment. -- Andrea Bolognani / Red Hat / Virtualization
