Storage consolidation due to server virtualization puts stringent new requirements on Storage Array (SA) performance. Virtualized workloads require new performance optimizations that cannot be totally addressed by merely using expensive hardware such as SSDs. This position paper presents Virtual Machine Disk Image (VMDI) introspection—a key technique for implementing a variety of virtualization...

In recent years, cloud computing technology has become one of the most significant IT infrastructures. Cloud users are increasing every day; thus, cloud must be able to handle the huge number of requests received at any given moment, causing concerns for resourced load balancing. The load balancing problem occurs when some cloud resources are overloaded with user tasks while other resources are...


 Modern virtual machine (VM) management software includes components that enable consolidation of VMs for power savings or load-balancing for performance. While the existing literature provides various methods for computing a better load-balanced, or consolidated goal state, it fails to adequately suggest the best path from the system's current state to the desired goal allocation. This paper ...

Dalvik virtual machine’s performance determines the performance of the Android platform. And each Dalvik virtual machine process is a Linux process, and each Dalvik virtual machine thread is a Linux thread. This paper analyses and researches process model of Android Dalvik virtual machine. Through research and analysis the role of Zygote in startup process of Dalvik virtual machine and the Zygo...

The virtual machine migration is core feature of virtualization that plays important role in cloud computing. The resource utilization is monitored by local migration agent that launches migration of virtual machine from one physical machine to another. Various virtual machine migration techniques are explored for efficient utilization of resources. With rapid increase in data centers, it becom...

Efficient resource management through the virtual machine placement (VMP) is a great concern in data centers. The Biobjective VPM is a representation of multi-objective combinatorial optimization problem. Energy or cost minimization of cloud data center is highly dependent upon the VMP policy. Allocating the set of virtual machines (VMs) to the set of suitable physical machines (PMs), while con...
