I can't speak to EC2. I have currently a rack full of OpenStack and our
actual production runs on bare metal vs. user-mode virtualized are
showing a 3.5% overhead for virtualization. These are older PowerEdge
1950 rack units and they're a bit strapped for RAM (only 2GB per core
right now) under load. Newer hardware with more ram per core would do
better.
