KVM Dirty Page Tracking - Peter Xu, Red Hat

Feedback form is now closed.
In this talk, Peter Xu will discuss the existing solutions used in KVM for guest dirty page tracking, challenges, and wild imaginations to the future. As a start, there will be a background introduction on what is KVM dirty page tracking, why we need it, and how it works. It will cover the state of the art techniques we already use with either dirty logging or dirty rings, meanwhile discuss pros and cons for different solutions. The challenges that we face on huge VM migrations will be discussed and explained too. It turns out that maybe having a better interface is not the only thing we need to do, but also think about how to use it right.
