virFileReadAllQuiet() sets errno, this would just overwrite it with
something less specific.
Good point. I've changed this to
if (virFileReadAllQuiet(procfile, 2048, &buf) < 0) {
/* This function already sets errno, so don't overwrite that
* and return immediately instead */
return -1;
}
so that some explanation for the choice is retained.

I think this check can be dropped. g_strsplit() doesn't ever return NULL
really, does it?
You're right, it doesn't. I've changed it.
The rest looks good.
Thanks for the review and for the very good suggestions!
I'll see whether I can get some feedback from KubeVirt developers
regarding whether or not this actually improves things for them
before pushing.
