A Novel Approach for Performance and Security Enhancement during Live Migration

Abstract

Objective: Cloud Computing facilitates Virtualization. The motivation of this study is to design a live migration scheme with negligible downtime. Method: The proposed method undergoes KVM post-copy migration. It stop the guest VM on source and send the machine states except guest RAM to the destination and resume the guest VM on destination and source pushes the memory pages to destination concurrently. In order to copy memory pages on-demand/background, Asynchronous Page Fault can be utilized. Proposed works also consider security during live migration. Live migration includes plenty of state transfer through the network. During migration, protecting the contents of VM state files is important. Proposed scheme implements virtual firewalling to protect the VM during migration. Findings: Post-copy live migration takes less downtime when compared with pre-copy migration based on the application running on the hosted VMs. Improvements: In future work, the amount of memory transfer rate will be reduced and also the implementation of virtual firewall can ensure authentication.
