I'm sorry, but you don't know what you are talking about. You pay for what you use. I don't own Amazon's servers either, but I pay for every bit of memory and CPU time that my EC2 instances use, and that includes the memory and CPU time consumed by my instance's kernel.

Ok, I'm a bit lost too. So, your question is the memory consumed by the VM kernel? The tradeoff is the ops overhead to manage the VM instance.
