Welcome To Ordinary Virtualization User!
I'll quickly confess that for a long time, I did not understand the excitement about virtualization.
What little I did get was that Virtualization was a software layer on top of an operating system that allowed the "hardware interface" to be "virtualized" so that a typical computer could run more than one operating system simultaneously. I could see the value in that for saving money, space, and power by consolidating the functions of multiple servers onto systems that had underutilized resources. But if you weren't a system administrator directly in charge of a lot of servers... Virtualization wasn't that big a deal.
But then I had a conversation one Saturday morning with a couple of Amateur Radio buddies (Thanks Ken K. and Bill V.) and the light started to come on about why Virtualization really was such a big deal, and why it mattered to "Ordinary Users".
