Virtualization technology provides a means for server consolidation, reducing the number of physical servers required for running a given workload. Virtual Machine (VM) live migration facilitates the transfer of a running (VM) between physical hosts while appearing transparent to the running application. Memory intensive applications tend to obstruct the original pre-copy live migration process and may result in the failure of the migration process due to its inability to transfer memory faster than memory is dirtied by the running application. The focus of this paper is to present several techniques that can be applied to both pre-copy live migration and post-copy live migration to better support migration of memory intensive applications.
