Virtual Machine (VM) migration is an appealing technique on nowadays cloud platforms to achieve high availability, load balancing and power saving. Unfortunately, migration of VM involves transferring a large amount of data, thereby imposing high overheads on network traffic, and consequently results in significant application performance degradation.

Rollback is an effective technique to resume the system execution from a recorded intermediate state upon failures. However, in virtualized environments, rollback of a virtual machine cluster (VMC) produces high network traffic and long service disruption, consequentially imposing significant overhead both on network and applications.
