[SATLUG] Choosing Virtualization technology

   I'd like to ask: how does one go about choosing which virtualization 
method or technology to use? What, for example, would suggest the use of 
a "Type 1" or "bare-metal" technology, such as Xen, over a "Type 2" 
method, such as VirtualBox?
I mean, given that the Type 1 requires a specialized kernel, isn't it 
just more hassle? Why does anyone even bother to use them? I'm thinking 
that the #1 reason is: better performance.
Then, within those general divisions, what motivates a particular 
choice? Why Xen instead of KVM? Why VirtualBox (which seems to be the 
favorite of this group) over VMWare (I mean the free stuff) or 
Parallels, or things I've read about but can't remember now?
I realize that there is a lot out there on this topic, and comparisons 
such as this one at WikiPedia:
It's good information, but, to me, rather overwhelming, and so I thought 
I'd ask this group to get some opinions and experiences.
