Virtualization can deliver significant benefits for cloud computing by enabling VM migration to improve utilization, balance load and alleviate hotspots. While several mechanisms exist to migrate VMs, few efforts have focused on optimizing migration policies in a multi-rooted tree datacenter network. The general problem has multiple facets, two of which map to generalizations of well-studied problems: migration of VMs in a bandwidth-oversubscribed tree network generalizes the maximum multi-commodity flow problem in a tree, and Migrations must meet load constraints at the servers, mapping to variants of the matching problem - generalized assignment and demand matching.
