[CentOS] OT: Why VM?

It has been a long thread, but one point that has been mentioned only in 
passing (VMWares "top 5 reasons") is cutting the electricity 
consumption. Maybe this is obvious.

I recently consolidated 8 hardware servers to a single 1U Dell, which 
runs KVM virtualization. The power bill was cut to a fraction! Do the 
same on a bigger scale, and it will be a significant saving. Also it 
reflects on cooling costs. Good for the planet, too.
