Yes, I know KVM is included, but at this stage XEN is the default and
when you use the Virtual Machine Manager, it uses XEN.

No, I'm not using VNC. My approach was from a single, non-networked
PC-point-of-view.
Someone who's never played with Virtual PC's and then opens up Virtual
Machine Manager thinking it would be cool to use, wouldn't think of
using VNC or something similar.

I thought, just for the fun of it, let's install Windows 2008 Small
Business Server.
Interestingly, using the same Virtual Machine Manager, the
installation wasn't as slow as with CentOS. It's almost asif it's more
optimized for Windows? I used the exact same settings for the
installation as with CentOS

Is this something you install on the PC, or does it improve network
access to the Virtual Machine?

That's what I had in mind as well. But, even just using a normal
monitor, keyboard, mouse and speakers - as connected to a normal PC's
would be nice as well.
What I'm getting at:
Can, or will virtualization replace dual boot systems or even give one
the ability to use your Desktop PC to it's full advantage?
For example, while I'm busy rendering a 3hour 3D scene in Maya
(running in Windows 7) I want to watch some moving in Linux - but have
both run in real-time. My PC is capable of it with 2x Corei7 CPU's &
16GB RAM. - this is just an example.
Differently put, we already do this with servers. One big & fast Quad
XEON can run many client's Virtual Machines, very easily. And many of
those Virtual Machines host a few hundred websites, thus saving a lot
on rack space, electricity, etc, etc.
How difficult will it really be todo the same on a normal Desktop PC,
with what's available on CentOS ATM?
