Postcopy live migration is yet another migration mechanism that allows users to change the execution host of a VM within one second while keeping visible disruption to a minimum. In addition, the whole migration process is basically shorter than normal live migration. It will provide great benefits for load balancing and energy savings using VMs. We have developed postcopy live migration whose quality is for production use and have evaluated its characteristic. Especially our implementation takes advantage of asynchronous page fault features which can't be utilized by precopy approach.
In this talk, I show new evaluation results of postcopy live migration and our analysis. The target audience is virtualization developers and advanced users who is looking for new features.
