Outline of Final Research Achievements

This project studied mechanisms to speed up the live migration of a group of virtual machines to a distant location. It aims at realizing safe server evacuation upon a disaster by exploiting a short period of time of backup power supply. We developed 1) a mechanism to transfer only updated states of a VM to a remote location upon a live migration, which is enabled by periodically sending the states of a VM during normal operation in a best-effort manner; 2) a mechanism to eliminate duplicated data in the data transferred during a live migration; 3) a mechanism that optimizes the scheduling of multiple live migrations to minimize an elapsed time of relocation of whole virtual machines; 4) a simulation mechanism of live migrations of virtual machines.
