Problem description

I tried to set up kube based on fedora coreos f31 on 3 libvirt machines (1 master, 2 workers). However, it was not possible because of a few glitches. But I was able to correct them.

Hence I set up a (none-)PR #5987 to document the changes which I needed. I'm unsure if this is/was a good idea. However my rationale is that it enables discussion about the changes that I have needed to get it running.
