Do they have the exact same versions of all packages, including
dependencies that might by "yum" updated by the Kubernetes
installation? Then the obvious test is to try a VM without Kubernetes
installed ahead of time, and/or to instlal Kubernetes on the hardware
platform and retest, isn't it?

I'll also admit that this is the point where I seriously value having
a PXE setup to allow me to re-install my hardware OS in a completely
controlled fashion and return my hardware to a well defined original
state. It can help ensure that even a casual "in passing change" is
cleared away for fresh testing, and it's part of why I appreciate
'mock' and similar tools lso much for providing clean build
environments.
