- Abstract
- As virtualization environment has been widespread and become popular, how to manage and operate a virtualization environment efficiently has emerged as a major concern. In fact, the operational issues of the virtualization environment, such as performance degradation or under-utilized resource management, can be controlled by managing the behaviors of guestOSes (also known as VMs). Therefore, it is necessary to identify the features of the guestOSes on the virtualization environment and apply the features to the VM management. In this paper, we propose a dynamic VM scheduling method using three VM control managers (performance, resource, and power manager). The proposed architecture classifies VMs considering performance factors of running threads and then provides the optimized environment for VM's workload. The resources of the VM are dynamically reconfigured for the best performance, and the power states are controlled for efficient power consumption. Through experiments, our method shows maximum 26% improved for the performance compared with the traditional Xen.
