Management and automation are important issues in enterprise environments,often consuming the largest fraction of the overall ITbudget. A key challenge here is co-ordination across multiple managementsolutions deployed in different management domains, includingacross hardware and software, across different levels of abstraction,and across different hosts. This paper makes three contributionsto addressing this problem. First, we propose a novel managementco-ordination architecture for virtualized environments.Our architecture includes two powerful abstractions – m-channels,which provide mechanisms for communication between the hardware,virtual machines, and applications and m-brokers, which allowhigh-level policy co-ordination across different managementagents. Second, we discuss Dom-M, an instantiation of our architecturein the context of the Xen hypervisor, and identify tradeoffsbetween different implementations of such management domains.Finally, to demonstrate the effectiveness of our approach, we implementand evaluate different cross-level solutions for power managementusing our abstractions, and also discuss qualitatively otherapplications including storage backup, inventory management, andtrust management.
