Kemari

Kemari is an implementation of Fault Tolerance feature using Xen hypervisor on top of commodity IA32 hardware.

Actually, I was in touch with the author of Kemari since the project was very early stage about 3 years ago. To tell the truth, I was doubtful if he can finish the plan he explained me in those days because the theme was too aggressive and he had limited time.

But, today I saw a live demo where a running Windows XP instance was migrated to another machine within seconds on a hardware crash (pressing the reset button) and continued playing video streaming.

His work, Kemari, will be merged into Xen 3.5, and furthermore, he seems to be working on porting Kemari to KVM.

Really impressive...
