Abstract

In order to optimize the using of server resources which host different services such as web services, this paper describes an adaptive and dynamic resource flowing scheme amongst VMs in a VM-based utility computing environment called ADVM (Adaptive and Dynamic Virtual Machine). In our scheme, VMs adjust their resources (CPU and memory) adaptively to share the physical resources efficiently. ADVM provides an on-the-fly, transparent and lazy resource flowing amongst VMs over a single server. By using dynamic priority and the strategy of adjusting resources, no VM interferes with others even via contention for some resources. To demonstrate the elegance of our strategy, we present a prototype implementation of ADVM. The experimental results indicate that ADVM effectively enforce the system performance based on Xen.*
