Well the cool kids like James Strachan and Kamesh Sampath are telling me
that xhyve is super awesome and I would be better looking, thinner and 10
years younger if I just tried it :-)

I do not even know what files to go delete...but I do see it misbehaving.

CDK 2.2+ uses more CPU than before - I stuck with CDK 2.1 until Jan 2017
for demos :-)

Now my demo volume (longer time spans between demos) is low enough that I
can afford to reset the demo on CDK 2.3+ for each presentation.

Just because :-)

It works...it is slower than it used to be and even with VirtualBox, it
does not survive as many sleep/wake cycles as it used to (CDK 2.1 days).
