Power-Aware Virtual Machine Scheduling-policy for Virtualized Heterogeneous Multicore Systems

This paper presents a systematic approach to correctly provision server resources in data centers, resulting in minimum energy consumption and SLA violations. In particular, we describe a hybrid method for efficient server provisioning in virtualized heterogeneous multicore Cloud data centers. The objective is to place VMs on host while keeping total utilization of CPU below defined threshold a...

Synchronization-Aware Virtual Machine Scheduling for Parallel Applications in Xen

In this paper, we propose a synchronization-aware VM scheduler for parallel applications in Xen. The proposed scheduler prevents threads from waiting for a significant amount of time during synchronization. For this purpose, we propose an identification scheme that can identify the threads that have awaited other threads for a long time. In this scheme, a detection module that can infer the int...

An Efficient Virtual CPU Scheduling Algorithm for Xen Hypervisor in Virtualized Environment

The core of virtualization is hypervisor which directly determines the platform performance. How to allocate resource effectively becomes an important problem. Xen is an open source hypervisor and used as a virtual machine monitor. In this paper, we designed an efficient virtual CPU scheduling algorithm that combined Deadline-Monotonic Scheduling with Simple Earliest Deadline First (EDF) schedu...
