title: virtual clock speed throttling on linux
body: <p>Throttling at will the execution and display speed of a particular process, for example, a game, a flash game, or an OpenGL game. I want to be able to slow it down to 20% or 0.5%. This is simply not possible on host space in linux. </p>
  
  <p>But linux supports two kernel-level virtualisation environments: <code>KVM</code> and <code>lxc</code>. </p>
  
  <p>Question: Is it possible to provide a fake system clock to a virtual lxc or KVM machine so that a flash game running in the guest will not run faster than what is set to run?</p>
