Chapter 15: Performance Tuning and Optimization for KVM VMs

When we're thinking about virtualization, there are always questions that keep coming up. Some of them might be simple enough, such as what are we going to get out of virtualization? Does it simplify things? Is it easier to back up? But there are also much more complex questions that start coming up once we've used virtualization for a while. How do we speed things up on a compute level? Is there a way to do more optimization? What can we tune additionally to get some more speed out of our storage or network? Can we introduce some configuration changes that will enable us to get more out of the existing infrastructure without investing a serious amount of money in it?

That's why performance tuning and optimization is so important to our virtualized environments. As we will find out in this chapter, there are loads of different parameters to consider – especially if we didn't design things properly...
