to fulfill service when gets accessed by end user. VM controlled by hypervisor also termed as VM Monitor (VMM). VMM manages VM execution, decides which VM to be selected for migration and how VM to be migrated. VM migration can be done by considering centralize VM migration or distributed approach. Once

Abstract-Both economic reasons and interoperation requirements necessitate the deployment of IaaS-clouds based on a share-nothing architecture. Here, live VM migration becomes a major impediment to achieving cloud-wide load balancing via selective and timely VM-migrations. Our approach is based

the majority of migration while OSes continue to run, we achieve impressive performance with minimal service downtimes; we demonstrate the migration of entire OS instances on a commodity cluster, recording service downtimes as low as 60ms. We show that that our performance is sufficient to make live migration

The number of nongonadal nuclei in the free-living soil nematode Caenorhabditis elegans increases from about 550 in the newly hatched larva to about 810 in the mature hermaphrodite and to about 970 in the mature male. The pattern of cell divisions which leads to this increase is essentially

Abstract—Live migration of virtual machines (VM) has recently become a key ingredient behind the management activities of cloud computing system to achieve the goals of load balancing, energy saving, failure recovery, and system maintenance. However, to our knowledge, most of the previous live VM

Abstract—System virtualization is becoming pervasive and it is enabling important new computing diagrams such as cloud computing. Live virtual machine (VM) migration is a unique capability of system virtualization which allows applications to be transparently moved across physical machines with a

tolerance. Moreover, live migration of VMs often allows workload movement with a short service downtime. However, service levels of running applications are likely to be negatively affected during a live VM migration. For this reason, a better understanding of its effects on system performance is highly

Live migration of virtual machines (VM) across distinct physical hosts provides a significant new benefit for administrators of data centers and clusters. However, previous memory-to-memory ap-proaches only make the live VM migration be applied in local area networks (LAN), and their im

to live migrate a VM originally running on one VMM to run on another VMM. In this paper, we propose Vagrant, a live migration framework which bridges the heterogeneity among diverse VMM abstractions and implementations. Vagrant supports the live migration of VMs across heterogeneous VMMs. We have

Open source Linux virtualization, such as Xen and KVM, has made great progress recently, and has been a hot topic in Linux world for years. With virtualization support, the hypervisor de-privileges operating systems as guest operating systems and shares physical resources among guests, such as memory and the network device. For device virtualization, some mechanisms are intro-duced for improving performance. Paravirtualized (PV) drivers are implemented to avoid excessive guest and hypervisor switching and thus achieve better perfor-mance, for example Xen’s split virtual network inter-face driver (VNIF). Unlike software optimization in PV driver, IOMMU, such as Intel R © Virtualization Technol-ogy for Directed I/O, AKA VT-d, enables direct passing
