Dirty Memory Tracking for Performant Checkpointing Solutions - Lei Cao, Stratus Technologies

Sign up or log in to save this to your schedule and see who's attending!

There are bottlenecks and limitations in KVM that hamper the performance of a checkpoint/rollback system, namely use of large bitmaps to track dirty memory and lack of multi thread support due to mmu lock implementation. In this presentation, I will discuss a new dirty memory tracking mechanism that improves the performance of checkpoint/rollback implementations for commercial production. This new mechanism can also be used to improve the predictability of live migration of memory write intensive workloads.
