Evaluating Intel Virtualization Technology FlexMigration With Multi-Generation Intel Multi-Core and Intel Dual-Core Xeon Processors

Executive Summary

In today's data centers, live migration is a required technology for building an agile, dynamic data center based on server virtualization. It has not been possible, however, to perform successful live migration between servers based on different generations of processors, each with different instruction sets. This limited our ability to implement large resource pools, creating islands of servers and hindering the implementation of advanced data center capabilities. Intel Virtualization Technology FlexMigration (Intel VT FlexMigration) assist and VMware's Enhanced VMotion are designed to overcome this limitation by enabling all servers to expose the same instruction set to applications, even if they are based on different processor generations from a single CPU supplier.
