    @wilderrodrigues My questions were not in the context of refactor at all. The reason for
asking the questions was to highlight the point that for testing config parameters you don't
need real hardware to test. And based on that the testing I did was sufficient to verify the
specific commit. So you see the questions were not rhetorical at all. Based on your comments
it looks like you never understood what I was trying to say.
    
    About testing with real hardware, it is only needed when you want to verify something
by actually accessing the VM OR some HV specific scenario needs to be tested. For e.g. ssh
to VM for validating certain properties of the VM OR verifying if some n/w rules etc. are
programmed properly in VR. Anything else can be run in both real hardware as well as simulator.
